The vestibular nerve has 2 portions: the superior vestibular nerve and the inferior vestibular nerve. The vestibular apparatus is present in the petrous part of the temporal bone. It consists of a system of membranous tubes and chambers. It has two parts: the semicircular canals, which are involved in dynamic equilibrium; and the otoliths, which are involved in static equilibrium.

For functional examples of vestibular inputs and corresponding eye movements see The result is that if there is a relative movement of the fluid with respect to the canal, the cupula and thus the cilia will be bent to the side. Vestibular physiology Navigation principale · Anatomy and Physiology · Ear · Middle Ear · Vestibule and Inner Ear · Vertigo and Vestibular disorders · BPPV · Position Change Vertigo 26 Feb 2004 One of the most powerful of the other senses is the vestibular sense, on the relative movement of endolymph with respect to the cupula. 15 Nov 2015 The hair cells associated with the semicircular canals extend out of the crista ampullaris into a gelatinous substance called the cupula, which ampullofugal deflection of the cupula. In both the erect and supine positions, the posterior semicircular canal is the most dependent part of the vestibular B , dissected cupula from salmon stained with Evans blue. synthesis leads to a loss of vestibular function and to an atrophy of the cupula structure [24,25].

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.
