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. The cupula acts as a membranous diaphragm, stretching from the crista to the opposite direction. Now during acceleration of head, as the membranous labyrinth is tethered to the skull, the crista and cupula accelerate with the head as The ampullary cupula is a gelatinous body overhanging the hair cells of the ampullary crests of the semicircular ducts; sensory hair cells are immersed in it and movement of endolymphatic fluid causes the cupula to move across the hair cells of the ampullary crest. Conclusions: Persistent geotropic nystagmus indicates a condition of a light cupula, which is accompanied by vestibular disability anda high incidence of pathological ﬁndings in the vestibular The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). In humans the vestibular nerve transmits sensory information transmitted by vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three semicircular canals via the vestibular ganglion of Scarpa. The vestibular system is a sensory system that is essential to normal movement and equilibrium.

We have described, in Paper I, a geotropic persistent direction-changing nystagmus (g-PCDN) in patients during vestibular crisis6. Instruct the patient to drop their head into flexion (approximately 30 degrees), and lean forward another 90 degrees. 30 degrees is required to move the canal parallel to floor, and then additional 90 degrees is required to position the cupula perpendicular to gravity. 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.

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. 14 hours ago The cupula, a thin vane, sits atop this crest, filling the lumen of the semicircular duct. The stereocilia of the hair cells are embedded in the gelatinous cupula.
