The vestibulocochlear nerve is part of the special senses group of cranial nerves and is made up of two components; the vestibular nerve and the cochlear nerve. The vestibular nerve is responsible for balance whilst the cochlear nerve is responsible for hearing. The nerves send impulses from the inner ear which contains the [[Ear_-_Anatomy_%26_Physiology#Vestibular_Receptors_and_Balance|vestibular apparatus]] and [[Ear_-_Anatomy_%26_Physiology#The_Cochlea|cochlear]]. The vestibulocochlear nerve is a sensory nerve made up of '''special somatic afferent fibres'''. It passes through the '''internal acoustic meatus''' and into the '''petrosal bone'''. The facial nerve also takes this route.

Clinical problems with the vestibulocochlear nerve would be indicated on examination by changes in hearing and/or horizontal and verticle eye movements (strabismus and nystagmus). A head tilt is also associated with this nerve.
