The vestibular nerve is one of the two branches of the Vestibulocochlear nerve (the cochlear nerve being the other). It goes to the semicircular canals via the vestibular ganglion. It receives positional information.
Axons of the vestibular nerve synapse in the vestibular nucleus on the lateral floor and wall of the fourth ventricle in the pons and medulla.
It arises from bipolar cells in the vestibular ganglion, ganglion of Scarpa, which is situated in the upper part of the outer end of the internal auditory meatus.
