Vestibular Nerve

The vestibular nerve is one of the two branches of the Vestibulocochlear nerve. It is made up of axons of bipolar cells in the vestibular ganglion, ganglion of Scarpa, which is located in the upper part of the outer end of the internal auditory meatus. The vestibular nerve travels to the semicircular canals, receiving positional and rotatory movement information and transmitting data to and from the brain that have to do with the regulation of the sense of balance. 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.
