vestibular system. The membranous labyrinth of the vestibular system, which contains the organs of balance— (lower left) the cristae of the semicircular ducts and (lower right) the maculae of the utricle and saccule. Encyclopædia Britannica, Inc. The cupula is a structure in the vestibular system, sensing proprioception. The cupula is located within the ampullae of each of the three semicircular canals . As fluid rushes by the cupula, hair cells within it sense rotational acceleration, and transmit the corresponding signal to the brain through the vestibulocochlear nerve (CN VIII) 14 timmar sedan · The vestibular receptor of cupula acts an important role in maintaining body balance.

The bony labyrinth consists of the cochlea, an oval cavity called the vestibule, and the semicircular As stated earlier, the vestibular system is present in the inner ear. It is present in a system of bony tubules and chambers present in the petrous part of temporal bone, a part of the skull. This system of bony tubules is called the bony labyrinth.

The … Using mixture theory, an axisymmetric continuum model is presented describing the response dynamics of the vestibular semicircular canals to canal-centered head rotation in which the cupula partition is modeled as a poroelastic mixture of interpenetrating solid and fluid constituents. The solid matrix of the cupula is assumed to behave as a linear elastic material, whereas the fluid In the vestibular function examination, CP did not appear in the heavy cupula group during the caloric testing, while 20% of the light cupula group had CP on the lesion side. The patients with heavy cupula were treated with repositioning maneuvers. Keywords: Vestibular, caloric, cupula, vestibulo-ocular reflex .

This model can demonstrate how […] Thalamic vestibular neurons project to cerebral cortex. Unilateral stimulation of the vestibular labyrinth results in mainly ipsilateral activation of vestibular cortex. In contrast to the other sensory systems, there is no unimodal primary vestibular cortex. That is, there is no cortical area that receives only vestibular input.

The anatomists of the 17th and 18th centuries assumed that the entire inner ear, including the vestibular apparatus, is devoted to hearing. It contains the sensory neuroepithelium, the crista ampullaris and is coated by the cupula, which is a gelatinous substance through which hair cells are embedded. The crista ampularis is a saddle shaped gelatinous structure along one wall of the membranous labyrinth and contains sensory hair cells of the vestibular system.
