The 3 semicircular canals are small, ringlike structures: lateral or horizontal, superior or anterior, and posterior or inferior. (medscape.com)
The posterior portion of the bony labyrinth contains the vestibule and the semicircular canals, and is responsible for equilibrium. (cloudaccess.net)
The neurosensory structures involved in hearing and equilibrium are located in the membranous labyrinth: the organ of Corti is located in the cochlear canal, while the maculae of the utricle and the saccule and the ampullae of the semicircular canals are located in the posterior section. (cloudaccess.net)
When you look left, the fluid in your semicircular canals moves, stimulating the ampulla at the end of the semicircular canal in the plane of movement. (thevertigodoctor.com)
Whole-cell patch-clamp recordings from calyx endings were performed in an in vitro whole-tissue preparation of the rat vestibular crista, the sensory organ of the semicircular canals that sense head rotation. (jneurosci.org)
Canal14
The mastoid air cells sit behind the bony portion of the canal (see the image below). (medscape.com)
Is only from the cerebral ominge, cbtrance of the posterior vertical canal and not without any ''reflex" movements. (trustingnews.org)
They are oriented at right angles to each other and are situated so that the superior and posterior canals are at 45° angles to the sagittal plane and the horizontal canal is 30° to the axial plane. (medscape.com)
however, the superior canal is paired with the contralateral posterior canal and vice versa. (medscape.com)
The nonampulated ends of the superior and posterior canal form the crus commune or common crus. (medscape.com)
They open into the vestibule by five apertures, since the medial end of the superior and the upper end of the posterior join to form a common canal or crus commune. (co.ma)
Its ampulla is anterior and lateral, and opens into the vestibule immediately above that of the lateral canal. (co.ma)
Its opposite extremity joins the non-ampullated end of the posterior canal to form the crus commune, which is about 4 mm. in length, and opens into the upper and medial part of the vestibule. (co.ma)
The posterior semicircular canal is the longest and measures from 18 to 22 mm. (co.ma)
while the superior canal of one ear is nearly parallel to the posterior canal of the other. (co.ma)
One was observed around the ampulla of the superior semicircular canal and utricle, and the other was observed around the ampulla of the posterior semicircular canal. (bvsalud.org)
In wild-type inner ears, Otx1 , but not Otx2 , was expressed in the lateral canal and ampulla, as well as part of the utricle. (biologists.com)
Paint-filled membranous labyrinths of Otx1 −/ − mutants showed an absence of the lateral semicircular canal, lateral ampulla, utriculosaccular duct and cochleosaccular duct, and a poorly defined hook (the proximal part) of the cochlea. (biologists.com)
However, within the inner ear, hOtx2 expression failed to rescue the lateral canal and ampulla phenotypes, and only variable rescues were observed in regions where both Otx1 and Otx2 are normally expressed. (biologists.com)
Anterior3
The arterial supply of the auricle is composed of the posterior auricular artery, the anterior auricular branch of the superficial temporal artery, and the occipital artery, which also contributes. (medscape.com)
The superior, anterior portions of the labia minora come together to encircle the clitoris (or glans clitoris), an organ that originates from the same cells as the glans penis and has abundant nerves that make it important in sexual sensation and orgasm. (edu.vn)
The outer walls of the anterior and posterior vagina are formed into longitudinal columns, or ridges, and the superior portion of the vagina-called the fornix-meets the protruding uterine cervix. (edu.vn)
Lateral1
They are distinguished from each other by their position, and are named superior, posterior, and lateral. (co.ma)
Organs2
Via cranial and spinal nerves (nerves of the Central and Peripheral nervous systems that relay sensory information to and from the brain and body), the different types of sensory receptor cells (such as mechanoreceptors, photoreceptors, chemoreceptors, thermoreceptors) in sensory organs transduct sensory information from these organs towards the central nervous system, finally arriving at the sensory cortices in the brain, where sensory signals are processed and interpreted (perceived). (wikipedia.org)
BC is the only current method for making fully functional, three-dimensional organs from pluripotent cells and generating human organs in large mammalian hosts may be able to address the critical worldwide problem of organ shortages for transplantation [ 16 ]. (biomedcentral.com)
Vestibule1
Its ampulla is placed inferiorly, and opens into the lower and back part of the vestibule, where may be seen about six or eight small apertures (macula cribrosa inferior), for the transmission of the nerves to this ampulla. (co.ma)
Extremity2
These two lamina are continuous with each other round the posterior extremity of the fissura vestibuli. (co.ma)
Differing slightly in length, each forms about two-thirds of a circle, one extremity of which is dilated and termed the osseous ampulla. (co.ma)
Synapses4
Using exogenous stem cells to replace lost inner ear neurons is a potential strategy if stem cell-derived neurons can form central and peripheral connections, form synapses on hair cells and cochlear nucleus neurons, and re-establish functional and tonotopic circuits [ 6 ]. (biomedcentral.com)
All auditory information is transduced by only 15,000 hair cells (organ of Corti), of which the so-called inner hair cells, numbering 3,500, are critically important, since they form synapses with approximately 90% of the 30,000 primary auditory neurons (figure 2). (cloudaccess.net)
In the vestibular periphery a unique postsynaptic terminal, the calyx, completely covers the basolateral walls of type I hair cells and receives input from multiple ribbon synapses. (jneurosci.org)
Type I hair cells contain ∼7-22 individual ribbon synapses per hair cell ( Lysakowski and Goldberg, 2008 ). (jneurosci.org)

In organisms, a sensory organ consists of a group of interrelated sensory cells that respond to a specific type of physical stimulus. (wikipedia.org)

This work validates the use of blastocyst complementation as a tool to create novel insight into the function of developmental genes and highlights blastocyst complementation as a potential platform for generating chimeric inner ear cell types that can be transplanted into damaged inner ears to improve hearing. (biomedcentral.com)
Hearing depends on the mechano-sensory hair cells (HCs) and their innervating neurons, the spiral ganglion neurons (SGNs), which are responsible for transmitting auditory information from the HCs in the organ of Corti to the cochlear nucleus in the brainstem. (biomedcentral.com)

Nerve4
When you look down into neck flexion, the otoconia slide forward with gravity, which pull the hair cells forward, and transmit a signal to your brain via your vestibulocochlear nerve. (thevertigodoctor.com)
In synapse, acetylcholine transmits the nerve impulse from the axon of one nerve cell to the dendrite of the other nerve cell. (mpboardguru.com)
Thus in the absence of acetylcholine from synapse nerve impulses do not pass from one nerve cell to other and thus transmission of nerve impulses is inhibited. (mpboardguru.com)
The largest branch (dendrite) of nerve cells is known as axon. (mpboardguru.com)
Neurons2
This research is the first to produce induced pluripotent stem cell-derived inner ear sensory neurons in the Neurog1 +/− heterozygote mouse using blastocyst complementation. (biomedcentral.com)
