Vestibulocochlear Nerve
Introduction
- The acoustic nerve is divided into two parts: the cochlear nerve and the vestibular nerve. Special equipment is needed to thoroughly examine the vestibular component, but some rudimentary examination can be performed to clinically determine the need for a referral.
