Eighth Cranial Nerve

Sometimes called the vestibulocochlear nerve. It divides into two parts—the cochlear (auditory) nerve responsible for hearing, and the vestibular nerve responsible for balance. This nerve carries hearing and balance information from the inner ear to the brain. If it is damaged or diseased, you could experience things such as hearing loss, tinnitus, hyperacusis, dizziness, loss of balance, vertigo, nausea and vomiting.
