Pathological processes of the inner ear (LABYRINTH) which contains the essential apparatus of hearing (COCHLEA) and balance (SEMICIRCULAR CANALS).
An oval, bony chamber of the inner ear, part of the bony labyrinth. It is continuous with bony COCHLEA anteriorly, and SEMICIRCULAR CANALS posteriorly. The vestibule contains two communicating sacs (utricle and saccule) of the balancing apparatus. The oval window on its lateral wall is occupied by the base of the STAPES of the MIDDLE EAR.
The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.
Three long canals (anterior, posterior, and lateral) of the bony labyrinth. They are set at right angles to each other and are situated posterosuperior to the vestibule of the bony labyrinth (VESTIBULAR LABYRINTH). The semicircular canals have five openings into the vestibule with one shared by the anterior and the posterior canals. Within the canals are the SEMICIRCULAR DUCTS.
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.
The part of the membranous labyrinth that traverses the bony vestibular aqueduct and emerges through the bone of posterior cranial fossa (CRANIAL FOSSA, POSTERIOR) where it expands into a blind pouch called the endolymphatic sac.
Pathological processes of the VESTIBULAR LABYRINTH which contains part of the balancing apparatus. Patients with vestibular diseases show instability and are at risk of frequent falls.

Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.
The vestibular part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The vestibular nerve fibers arise from neurons of Scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the VESTIBULAR NUCLEI of the BRAIN STEM. These fibers mediate the sense of balance and head position.
The blind pouch at the end of the endolymphatic duct. It is a storage reservoir for excess ENDOLYMPH, formed by the blood vessels in the membranous labyrinth.
Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).

3D MRI of the membranous labyrinth. An age related comparison of MR findings in patients with labyrinthine fibrosis and in persons without inner ear symptoms. (1/121)

PURPOSE: We compared MRI of the membranous labyrinth in patients with chronic non-neoplastic inner ear disease and MR signs of labyrinthine fibrosis and controls depending on their age, in order to establish whether there were any MR differences regarding patient age groups, control age groups and between the patients and controls themselves. MATERIALS AND METHODS: Clinical ENT examinations as well as a T2* weighted 3D CISS (Constructive Interference in Steady State) sequence with a slice thickness of 0.7 mm were performed. Our collective was subdivided as follows: 0-19 years (10 controls, 3 patients with chronic non-neoplastic inner ear disease), 20-49 years (55 controls, 8 patients), 50 years and older (40 controls, 22 patients). Detectability of labyrinthine structures (e.g. cochlea, vestibule, semicircular canals) and filling defects were evaluated. RESULTS: In the 3 age-groups of the control collective no significant differences were observed in the membranous labyrinth. However differences concerning labyrinthine detectability emerged between controls and patients in both the 20-49 years and 50 years and older age groups. In the patient collective the 3 age groups showed no significant discrepancy in the mean number of lesions. CONCLUSION: Filling defects of the membranous labyrinth on 3D CISS MR images are pathological even in older persons. We would therefore recommend high resolution T2* weighted MRI in the case of suspected labyrinthine fibrosis.  (+info)

Sound- and pressure-induced vertigo associated with dehiscence of the roof of the superior semicircular canal. (2/121)

In many types of peripheral vertigo, imaging is not part of the initial evaluation. We present a patient with sound- and pressure-induced vertigo associated with bony dehiscence of the roof of the superior semicircular canal. The diagnosis of this new entity can only be made by high-resolution coronal CT imaging of the temporal bones. In patients with this symptom complex, CT should be performed early in the diagnostic workup.  (+info)

Cavernous angioma of the internal acoustic meatus--case report. (3/121)

A 39-year-old female presented with an intrameatal cavernous angioma manifesting as hearing loss and tinnitus in the right ear which progressed over 8 months. Magnetic resonance (MR) images revealed an intrameatal lesion as ultra-high intensity, nearly as bright as cerebrospinal fluid, on the T2-weighted images, and isointensity on the T1-weighted images. Computed tomography (CT) showed the mass accompanied by stippled patterns of calcification. The patient underwent surgery under a diagnosis of calcified acoustic neurinoma. Histological studies were compatible with cavernous angioma. Intrameatal cavernous angioma is a rare disease which requires differential diagnosis from the more common neurinoma or meningioma in this location. Intrameatal lesion with ultra-high intensity on T2-weighted MR imaging and stippled patterns of calcification on CT is more likely to be cavernous angioma than acoustic neurinoma. These neuroimaging features are important information in deciding the treatment strategy.  (+info)

Coriolis-force-induced trajectory and endpoint deviations in the reaching movements of labyrinthine-defective subjects. (4/121)

When reaching movements are made during passive constant velocity body rotation, inertial Coriolis accelerations are generated that displace both movement paths and endpoints in their direction. These findings directly contradict equilibrium point theories of movement control. However, it has been argued that these movement errors relate to subjects sensing their body rotation through continuing vestibular activity and making corrective movements. In the present study, we evaluated the reaching movements of five labyrinthine-defective subjects (lacking both semicircular canal and otolith function) who cannot sense passive body rotation in the dark and five age-matched, normal control subjects. Each pointed 40 times in complete darkness to the location of a just extinguished visual target before, during, and after constant velocity rotation at 10 rpm in the center of a fully enclosed slow rotation room. All subjects, including the normal controls, always felt completely stationary when making their movements. During rotation, both groups initially showed large deviations of their movement paths and endpoints in the direction of the transient Coriolis forces generated by their movements. With additional per-rotation movements, both groups showed complete adaptation of movement curvature (restoration of straight-line reaches) during rotation. The labyrinthine-defective subjects, however, failed to regain fully accurate movement endpoints after 40 reaches, unlike the control subjects who did so within 11 reaches. Postrotation, both groups' movements initially had mirror image curvatures to their initial per-rotation reaches; the endpoint aftereffects were significantly different from prerotation baseline for the control subjects but not for the labyrinthine-defective subjects reflecting the smaller amount of endpoint adaptation they achieved during rotation. The labyrinthine-defective subjects' movements had significantly lower peak velocity, higher peak elevation, lower terminal velocity, and a more vertical touchdown than those of the control subjects. Thus the way their reaches terminated denied them the somatosensory contact cues necessary for full endpoint adaptation. These findings fully contradict equilibrium point theories of movement control. They emphasize the importance of contact cues in adaptive movement control and indicate that movement errors generated by Coriolis perturbations of limb movements reveal characteristics of motor planning and adaptation in both healthy and clinical populations.  (+info)

Dumbbell schwannomas of the internal auditory canal. (5/121)

BACKGROUND AND PURPOSE: Benign tumors of the internal auditory canal (IAC) may leave the confines of the IAC fundus and extend into inner ear structures, forming a dumbbell-shaped lesion. It is important to differentiate dumbbell lesions, which include facial and vestibulocochlear schwannomas, from simple intracanalicular schwannomas, as surgical techniques and prognostic implications are affected. In this article, the imaging and clinical features of these dumbbell schwannomas are described. METHODS: A dumbbell lesion of the IAC is defined as a mass with two bulbous segments, one in the IAC fundus and the other in the membranous labyrinth of the inner ear or the geniculate ganglion of the facial nerve canal, spanned by an isthmus. Twenty-four patients with dumbbell lesions of the IAC had their clinical and imaging data retrospectively reviewed. Images were evaluated for contour of the mass and extension into the membranous labyrinth or geniculate ganglion. RESULTS: Ten of 24 lesions were facial nerve dumbbell lesions. Characteristic features included an enhancing "tail" along the labyrinthine segment of the facial nerve and enlargement of the facial nerve canal. Dumbbell schwannomas of the vestibulocochlear nerve (14/24) included transmodiolar (8/14), which extended into the cochlea, transmacular (2/14), which extended into the vestibule, and combined transmodiolar/transmacular (4/14) types. CONCLUSION: Simple intracanalicular schwannomas can be differentiated from transmodiolar, transmacular, and facial nerve schwannomas with postcontrast and high-resolution fast spin-echo T2-weighted MR imaging. Temporal bone CT is reserved for presurgical planning in the dumbbell facial nerve schwannoma group.  (+info)

Enhancement of the eighth cranial nerve and labyrinth on MR imaging in sudden sensorineural hearing loss associated with human herpesvirus 1 infection: case report. (6/121)

The case of a 61-year-old woman who presented with herpes labialis, subclinical meningitis, and sudden onset of bilateral sensorineural hearing loss is presented. Contrast-enhanced MR imaging showed marked bilateral enhancement of the intracanalicular portion of the eighth cranial nerve, right cochlea, and left vestibule. Polymerase chain reaction was positive for human herpesvirus 1 obtained from the cerebral spinal fluid, which suggested the diagnosis of viral neuritis.  (+info)

Positional down beating nystagmus in 50 patients: cerebellar disorders and possible anterior semicircular canalithiasis. (7/121)

OBJECTIVES: To clarify the clinical significance of positional down beat nystagmus (pDBN). METHODS: A discussion of the neuro-otological findings in 50 consecutive patients with pDBN. RESULTS: In 38 patients there was evidence of CNS disease (central group) but in 12 there was not (idiopathic group). In the CNS group, presenting symptoms were gait, speech, and autonomic dysfunction whereas in the idiopathic group patients mostly reported positional vertigo. The main neurological and oculomotor signs in the CNS group were explained by cerebellar dysfunction, including 13 patients with multiple system atrophy. In patients with multiple system atrophy with a prominent extrapyramidal component, the presence of pDBN was helpful in the differential diagnosis of atypical parkinsonism. No patient with pDBN had the Arnold-Chiari malformation, a common cause of constant down beat nystagmus (DBN). In the idiopathic group, the pDBN had characteristics which suggested a peripheral labyrinthine disorder: vertigo, adaptation, and habituation. In six patients an additional torsional component was found (concurrently with the pDBN in three). Features unusual for peripheral disorder were: bilateral positive Dix-Hallpike manoeuvre in nine of 12 patients and selective provocation by the straight head-hanging manoeuvre in two. CONCLUSION: It is argued that some patients with idiopathic pDBN have benign paroxysmal positional vertigo (BPPV) with lithiasis of the anterior canal. The torsional component may be weak, because of the predominantly sagittal orientation of the anterior canal, and may not be readily seen clinically. Nystagmus provocation by bilateral Dix-Hallpike and straight head-hanging may be explained by the vertical upwards orientation of the ampullary segment of the anterior canal in the normal upright head position. Such orientation makes right-left specificity with the Dix-Hallpike manoeuvre less important than for posterior canal BPPV. This orientation requires a further downwards movement of the head, often achieved with the straight head-hanging position, to provoke migration of the canaliths. The straight head-hanging manoeuvre should be carried out in all patients with a history of positional vertigo and a negative Dix-Hallpike manoeuvre.  (+info)

Vestibular information is required for dead reckoning in the rat. (8/121)

Dead reckoning is an on-line form of spatial navigation used by an animal to identify its present location and return directly to a starting location, even after circuitous outward trips. At present, it is not known which of several self-movement cues (efferent copy from movement commands, proprioceptive information, sensory flow, or vestibular information) are used to compute homeward trajectories. To determine whether vestibular information is important for dead reckoning, the impact of chemical labyrinthectomy was evaluated in a test that demanded on-line computation of a homeward trajectory. Rats were habituated to leave a refuge that was visible from all locations on a circular table to forage for large food pellets, which they carried back to the refuge to eat. Two different probe trials were given: (1) the rats foraged from the same spatial location from a hidden refuge in the light and so were able to use visual cues to navigate; (2) the same procedure took place in the dark, constraining the animals to dead reckon. Although control rats carried food directly and rapidly back to the refuge on both probes, the rats with vestibular lesions were able to do so on the hidden refuge but not on the dark probe. The scores of vestibular reflex tests predicted the dead reckoning deficit. The vestibular animals were also impaired in learning a new piloting task. This is the first unambiguous demonstration that vestibular information is used in dead reckoning and also contributes to piloting.  (+info)

Labyrinth diseases refer to conditions that affect the inner ear's labyrinth, which is the complex system of fluid-filled channels and sacs responsible for maintaining balance and hearing. These diseases can cause symptoms such as vertigo (a spinning sensation), dizziness, nausea, hearing loss, and tinnitus (ringing in the ears). Examples of labyrinth diseases include Meniere's disease, labyrinthitis, vestibular neuronitis, and benign paroxysmal positional vertigo. Treatment for these conditions varies depending on the specific diagnosis but may include medications, physical therapy, or surgery.

The vestibular system is a part of the inner ear that contributes to our sense of balance and spatial orientation. It is made up of two main components: the vestibule and the labyrinth.

The vestibule is a bony chamber in the inner ear that contains two important structures called the utricle and saccule. These structures contain hair cells and fluid-filled sacs that help detect changes in head position and movement, allowing us to maintain our balance and orientation in space.

The labyrinth, on the other hand, is a more complex structure that includes the vestibule as well as three semicircular canals. These canals are also filled with fluid and contain hair cells that detect rotational movements of the head. Together, the vestibule and labyrinth work together to provide us with information about our body's position and movement in space.

Overall, the vestibular system plays a crucial role in maintaining our balance, coordinating our movements, and helping us navigate through our environment.

The inner ear is the innermost part of the ear that contains the sensory organs for hearing and balance. It consists of a complex system of fluid-filled tubes and sacs called the vestibular system, which is responsible for maintaining balance and spatial orientation, and the cochlea, a spiral-shaped organ that converts sound vibrations into electrical signals that are sent to the brain.

The inner ear is located deep within the temporal bone of the skull and is protected by a bony labyrinth. The vestibular system includes the semicircular canals, which detect rotational movements of the head, and the otolith organs (the saccule and utricle), which detect linear acceleration and gravity.

Damage to the inner ear can result in hearing loss, tinnitus (ringing in the ears), vertigo (a spinning sensation), and balance problems.

The semicircular canals are part of the vestibular system in the inner ear that contributes to the sense of balance and spatial orientation. They are composed of three fluid-filled tubes, each located in a different plane (anterior, posterior, and horizontal) and arranged at approximately right angles to each other. The semicircular canals detect rotational movements of the head, enabling us to maintain our equilibrium during movement.

When the head moves, the fluid within the semicircular canals moves in response to that motion. At the end of each canal is a structure called the ampulla, which contains hair cells with hair-like projections (stereocilia) embedded in a gelatinous substance. As the fluid moves, it bends the stereocilia, stimulating the hair cells and sending signals to the brain via the vestibular nerve. The brain then interprets these signals to determine the direction and speed of head movement, allowing us to maintain our balance and orientation in space.

The placenta is an organ that develops in the uterus during pregnancy and provides oxygen and nutrients to the growing baby through the umbilical cord. It also removes waste products from the baby's blood. The placenta attaches to the wall of the uterus, and the baby's side of the placenta contains many tiny blood vessels that connect to the baby's circulatory system. This allows for the exchange of oxygen, nutrients, and waste between the mother's and baby's blood. After the baby is born, the placenta is usually expelled from the uterus in a process called afterbirth.

Placentation is the process by which the placenta, an organ that provides nutrients and oxygen to the developing fetus and removes waste products, is formed and develops during pregnancy. It involves the attachment of the fertilized egg (embryo) to the uterine wall and the development of specialized structures that facilitate the exchange of gases, nutrients, and waste between the mother and the fetus.

In humans, placentation begins when the embryo implants into the endometrium, or the lining of the uterus, about 6-10 days after fertilization. The outer layer of the embryo, called the trophoblast, invades the endometrial tissue and forms a structure called the placenta.

The placenta consists of both maternal and fetal tissues. The fetal portion of the placenta is derived from the chorionic villi, which are finger-like projections that develop on the surface of the embryo and increase the surface area for exchange. The maternal portion of the placenta is made up of modified endometrial tissue called decidua.

The placenta grows and develops throughout pregnancy, providing a vital connection between the mother and fetus. Proper placentation is essential for a healthy pregnancy and fetal development. Abnormalities in placentation can lead to complications such as preeclampsia, preterm labor, and intrauterine growth restriction.

The endolymphatic duct is a narrow canal in the inner ear that is part of the membranous labyrinth. It connects the utricle and saccule (two sensory structures in the vestibular system responsible for detecting changes in head position and movement) to the endolymphatic sac (a dilated portion of the duct that helps regulate the volume and pressure of endolymph, a fluid found within the membranous labyrinth).

The endolymphatic duct plays a crucial role in maintaining the balance and homeostasis of the inner ear by allowing the absorption and circulation of endolymph. Disorders or abnormalities in this region can lead to various vestibular and hearing dysfunctions, such as Meniere's disease, endolymphatic hydrops, and other inner ear disorders.

Vestibular diseases are a group of disorders that affect the vestibular system, which is responsible for maintaining balance and spatial orientation. The vestibular system includes the inner ear and parts of the brain that process sensory information related to movement and position.

These diseases can cause symptoms such as vertigo (a spinning sensation), dizziness, imbalance, nausea, and visual disturbances. Examples of vestibular diseases include:

1. Benign paroxysmal positional vertigo (BPPV): a condition in which small crystals in the inner ear become dislodged and cause brief episodes of vertigo triggered by changes in head position.
2. Labyrinthitis: an inner ear infection that can cause sudden onset of vertigo, hearing loss, and tinnitus (ringing in the ears).
3. Vestibular neuronitis: inflammation of the vestibular nerve that causes severe vertigo, nausea, and imbalance but typically spares hearing.
4. Meniere's disease: a disorder characterized by recurrent episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the affected ear.
5. Vestibular migraine: a type of migraine that includes vestibular symptoms such as dizziness, imbalance, and disorientation.
6. Superior canal dehiscence syndrome: a condition in which there is a thinning or absence of bone over the superior semicircular canal in the inner ear, leading to vertigo, sound- or pressure-induced dizziness, and hearing loss.
7. Bilateral vestibular hypofunction: reduced function of both vestibular systems, causing chronic imbalance, unsteadiness, and visual disturbances.

Treatment for vestibular diseases varies depending on the specific diagnosis but may include medication, physical therapy, surgery, or a combination of these approaches.

The vestibular nucleus, lateral, is a part of the vestibular nuclei complex located in the medulla oblongata region of the brainstem. It plays a crucial role in the processing and integration of vestibular information related to balance, posture, and eye movements. The lateral vestibular nucleus is primarily involved in the regulation of muscle tone and coordinating head and eye movements during changes in body position or movement. Damage to this area can result in various vestibular disorders, such as vertigo, oscillopsia, and balance difficulties.

The vestibular nuclei are clusters of neurons located in the brainstem that receive and process information from the vestibular system, which is responsible for maintaining balance and spatial orientation. The vestibular nuclei help to coordinate movements of the eyes, head, and body in response to changes in position or movement. They also play a role in reflexes that help to maintain posture and stabilize vision during head movement. There are four main vestibular nuclei: the medial, lateral, superior, and inferior vestibular nuclei.

The petrous bone is a part of the temporal bone, one of the 22 bones in the human skull. It is a thick and irregularly shaped bone located at the base of the skull and forms part of the ear and the cranial cavity. The petrous bone contains the cochlea, vestibule, and semicircular canals of the inner ear, which are responsible for hearing and balance. It also helps protect the brain from injury by forming part of the bony structure surrounding the brain.

The term "petrous" comes from the Latin word "petrosus," meaning "stony" or "rock-like," which describes the hard and dense nature of this bone. The petrous bone is one of the densest bones in the human body, making it highly resistant to fractures and other forms of damage.

In medical terminology, the term "petrous" may also be used to describe any structure that resembles a rock or is hard and dense, such as the petrous apex, which refers to the portion of the petrous bone that points towards the sphenoid bone.

Caloric tests are a type of diagnostic test used in otology and neurotology to evaluate the function of the vestibular system, which is responsible for maintaining balance and eye movements. The tests involve stimulating the vestibular system with warm or cool air or water, and then observing and measuring the resulting eye movements.

During the test, the patient sits in a chair with their head tilted back at a 30-degree angle. A special goggles device is placed over their eyes to measure and record eye movements. Then, warm or cool air or water is introduced into each ear canal, alternately, for about 20-30 seconds.

The stimulation of the inner ear with warm or cold temperatures creates a difference in temperature between the inner ear and the brain, which activates the vestibular system and causes eye movements called nystagmus. The direction and intensity of the nystagmus are then analyzed to determine if there is any damage or dysfunction in the vestibular system.

Caloric tests can help identify lesions in the vestibular system, such as vestibular neuritis or labyrinthitis, and can also help differentiate between peripheral and central vestibular disorders.

The vestibular nerve, also known as the vestibulocochlear nerve or cranial nerve VIII, is a pair of nerves that transmit sensory information from the balance-sensing structures in the inner ear (the utricle, saccule, and semicircular canals) to the brain. This information helps the brain maintain balance and orientation of the head in space. The vestibular nerve also plays a role in hearing by transmitting sound signals from the cochlea to the brain.

The endolymphatic sac is a small, fluid-filled structure that is part of the inner ear. It is located near the vestibular aqueduct and is responsible for maintaining the balance of fluids in the inner ear. The endolymphatic sac also plays a role in the resorption of endolymph, which is the fluid that fills the membranous labyrinth of the inner ear. Disorders of the endolymphatic sac can lead to conditions such as Meniere's disease, which is characterized by vertigo, hearing loss, and tinnitus.

Trophoblasts are specialized cells that make up the outer layer of a blastocyst, which is a hollow ball of cells that forms in the earliest stages of embryonic development. In humans, this process occurs about 5-6 days after fertilization. The blastocyst consists of an inner cell mass (which will eventually become the embryo) and an outer layer of trophoblasts.

Trophoblasts play a crucial role in implantation, which is the process by which the blastocyst attaches to and invades the lining of the uterus. Once implanted, the trophoblasts differentiate into two main layers: the cytotrophoblasts (which are closer to the inner cell mass) and the syncytiotrophoblasts (which form a multinucleated layer that is in direct contact with the maternal tissues).

The cytotrophoblasts proliferate and fuse to form the syncytiotrophoblasts, which have several important functions. They secrete enzymes that help to degrade and remodel the extracellular matrix of the uterine lining, allowing the blastocyst to implant more deeply. They also form a barrier between the maternal and fetal tissues, helping to protect the developing embryo from the mother's immune system.

Additionally, trophoblasts are responsible for the formation of the placenta, which provides nutrients and oxygen to the developing fetus and removes waste products. The syncytiotrophoblasts in particular play a key role in this process by secreting hormones such as human chorionic gonadotropin (hCG), which helps to maintain pregnancy, and by forming blood vessels that allow for the exchange of nutrients and waste between the mother and fetus.

Abnormalities in trophoblast development or function can lead to a variety of pregnancy-related complications, including preeclampsia, intrauterine growth restriction, and gestational trophoblastic diseases such as hydatidiform moles and choriocarcinomas.

I apologize for any confusion, but "Hydrocharitaceae" is not a medical term. It is a taxonomic category in botany, specifically a family of aquatic plants known as the Hydrocharitaceae family. This family includes various genera of submerged, floating, and emergent aquatic plants, such as hydrillas, tape grasses, and water poppies.

If you have any medical terms or concepts that you would like me to define or explain, please let me know!

'Fenestration, Labyrinth' is not a medical term that refers to a specific condition or diagnosis. However, I can provide you with some information about the individual terms:

1. Fenestration: In anatomy and physiology, fenestration refers to the presence of small windows or openings in a structure, usually in a blood vessel wall or within the inner ear. These openings allow for the passage of fluids, gases, or sound waves.

2. Labyrinth: The labyrinth is an anatomical term that describes a complex network of interconnected channels and cavities found primarily in two locations: the inner ear and certain structures within the brain.

In the inner ear, the bony labyrinth consists of three main parts: the vestibule, semicircular canals, and cochlea. These structures contain fluid-filled ducts and sacs that help maintain balance and transmit sound to the brain. The membranous labyrinth is a network of tubes and sacs within the bony labyrinth, containing endolymph fluid.

In summary, 'Fenestration, Labyrinth' may refer to the presence of fenestrations or openings in the structures of the labyrinth found in the inner ear. However, it is not a widely used medical term and does not have a specific definition within the field of medicine.

The cochlea is a part of the inner ear that is responsible for hearing. It is a spiral-shaped structure that looks like a snail shell and is filled with fluid. The cochlea contains hair cells, which are specialized sensory cells that convert sound vibrations into electrical signals that are sent to the brain.

The cochlea has three main parts: the vestibular canal, the tympanic canal, and the cochlear duct. Sound waves enter the inner ear and cause the fluid in the cochlea to move, which in turn causes the hair cells to bend. This bending motion stimulates the hair cells to generate electrical signals that are sent to the brain via the auditory nerve.

The brain then interprets these signals as sound, allowing us to hear and understand speech, music, and other sounds in our environment. Damage to the hair cells or other structures in the cochlea can lead to hearing loss or deafness.

Endolymph is a specific type of fluid that is found within the inner ear, more specifically in the membranous labyrinth of the inner ear. This fluid plays a crucial role in maintaining balance and hearing functions. It helps in the stimulation of hair cells present in the inner ear which then transmit signals to the brain, enabling us to hear and maintain our balance. Any disturbance or changes in the composition or flow of endolymph can lead to various vestibular disorders and hearing problems.

Embryo loss is a medical term that refers to the miscarriage or spontaneous abortion of an embryo, which is the developing offspring from the time of fertilization until the end of the eighth week of pregnancy. Embryo loss can occur at any point during this period and may be caused by various factors such as chromosomal abnormalities, maternal health issues, infections, environmental factors, or lifestyle habits.

Embryo loss is a common occurrence, with up to 30% of pregnancies ending in miscarriage, many of which happen before the woman even realizes she is pregnant. In most cases, embryo loss is a natural process that occurs when the body detects an abnormality or problem with the developing embryo and terminates the pregnancy to prevent further complications. However, recurrent embryo loss can be a sign of underlying medical issues and may require further evaluation and treatment.

A vestibulo-ocular reflex (VOR) is a automatic motion of the eyes that helps to stabilize images on the retina during head movement. It is mediated by the vestibular system, which includes the semicircular canals and otolith organs in the inner ear.

When the head moves, the movement is detected by the vestibular system, which sends signals to the oculomotor nuclei in the brainstem. These nuclei then generate an eye movement that is equal and opposite to the head movement, allowing the eyes to remain fixed on a target while the head is moving. This reflex helps to maintain visual stability during head movements and is essential for activities such as reading, walking, and driving.

The VOR can be tested clinically by having the patient follow a target with their eyes while their head is moved passively. If the VOR is functioning properly, the eyes should remain fixed on the target despite the head movement. Abnormalities in the VOR can indicate problems with the vestibular system or the brainstem.

Cochlear diseases refer to conditions that affect the structure or function of the cochlea, which is a part of the inner ear responsible for hearing. These diseases can cause various types and degrees of hearing loss, ranging from mild to profound. Some common cochlear diseases include:

1. Cochlear otosclerosis: A condition where there is abnormal bone growth in the cochlea, which can lead to conductive or sensorineural hearing loss.
2. Cochlear Meniere's disease: A disorder that affects the inner ear and causes vertigo, tinnitus, and fluctuating hearing loss.
3. Cochlear damage due to exposure to loud noises: Prolonged or sudden exposure to loud noises can cause permanent cochlear damage and hearing loss.
4. Presbycusis: Age-related hearing loss that affects the cochlea and other structures of the auditory system.
5. Cochlear nerve tumors: Rare benign or malignant growths on the cochlear nerve can cause hearing loss, tinnitus, and balance problems.
6. Infections: Bacterial or viral infections such as meningitis, labyrinthitis, or otitis media can damage the cochlea and lead to hearing loss.
7. Ototoxicity: Certain medications can be toxic to the cochlea and cause hearing loss, tinnitus, or balance problems.
8. Genetic factors: Inherited genetic mutations can cause various types of cochlear diseases, such as connexin 26 deficiency, Waardenburg syndrome, or Usher syndrome.

It is important to note that early diagnosis and treatment of cochlear diseases can help prevent or minimize hearing loss and other complications.

Pregnancy is a physiological state or condition where a fertilized egg (zygote) successfully implants and grows in the uterus of a woman, leading to the development of an embryo and finally a fetus. This process typically spans approximately 40 weeks, divided into three trimesters, and culminates in childbirth. Throughout this period, numerous hormonal and physical changes occur to support the growing offspring, including uterine enlargement, breast development, and various maternal adaptations to ensure the fetus's optimal growth and well-being.

Labyrinthitis is a medical condition characterized by inflammation of the labyrinth, which is the inner ear's balance- and hearing-sensitive system. It is often caused by an infection, such as a viral or bacterial infection, that spreads to the inner ear. The inflammation can affect the delicate structures of the labyrinth, leading to symptoms such as vertigo (a spinning sensation), dizziness, imbalance, hearing loss, and tinnitus (ringing in the ears). Labyrinthitis can be a serious condition that requires medical attention and treatment.

Vertigo is a specific type of dizziness characterized by the sensation that you or your surroundings are spinning or moving, even when you're perfectly still. It's often caused by issues with the inner ear or the balance-sensing systems of the body. Vertigo can be brought on by various conditions, such as benign paroxysmal positional vertigo (BPPV), labyrinthitis, vestibular neuritis, Meniere's disease, and migraines. In some cases, vertigo may also result from head or neck injuries, brain disorders like stroke or tumors, or certain medications. Treatment for vertigo depends on the underlying cause and can include specific exercises, medication, or surgery in severe cases.
