The vestibulocochlear nerve auditory vestibular nerve , known as the eighth cranial nerve , transmits sound and equilibrium balance information from the inner ear to the brain. The vestibulocochlear nerve consists mostly of bipolar neurons and splits into two large divisions: the cochlear nerve and the vestibular nerve. Cranial nerve 8, the vestibulocochlear nerve, goes to the middle portion of the brainstem called the pons, which then is largely composed of fibers going to the cerebellum. The 8th cranial nerve runs between the base of the pons the middle portion of the brainstem and medulla oblongata the lower portion of the brainstem. This junction between the pons, medulla, and cerebellum that contains the 8th nerve is called the cerebellopontine angle. The vestibulocochlear nerve is accompanied by the labyrinthine artery , which usually branches off from the anterior inferior cerebellar artery AICA at the cerebellopontine angle , and then goes with the 8th nerve through the internal acoustic meatus to the internal ear.

Before the development of electroacoustic equipment for generating and measuring sound , the available tests of hearing gave approximate answers at best. The examiner also might note the length of time the person could hear the gradually diminishing note of a tuning fork , comparing the performance with his own. A qualitative assessment of hearing loss can be carried out with a tuning fork. Such tests exploit the ability of sound to be conducted through the bones of the skull. In the Rinne test the sounding tuning fork is placed on the mastoid process , and the person being tested is asked to report when it is no longer heard. The examiner then removes the fork immediately and holds the prongs close to the open ear canal.

Assessment - Cranial Nerves - Cranial Nerve 8 -- Auditory Acuity, Weber & Rinne Tests

Cranial nerve VIII brings sound and information about one's position and movement in space into the brain. The auditory and vestibular systems subserve several functions basic to clinical medicine and to psychiatry. This article covers the basics of cranial nerve VIII, hearing and vestibular systems, including common problems with hearing and balance, problems with hearing and balance that tend to be found in psychiatric patients, and some simple assessments of value in clinical practice.

The Weber and Rinne tests assess balance and equilibrium. True. True or False ( correct if False): The six extraocular muscles move the eyeball. True.
