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.
