- Vestibulocochlear nerve
- A nerve that is responsible for the sense of hearing and which is also pertinent to balance, to the body position sense. Problems with the vestibulocochlear nerve may result in deafness, tinnitus (ringing or noise in the ears), dizziness, vertigo and vomiting. The vestibulocochlear nerve is the eighth cranial nerve. The 12 cranial nerves, the vestibulocochlear nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.

* * *the eighth cranial nerve (VIII), responsible for carrying sensory impulses from the inner ear to the brain. It has two branches, the vestibular nerve and the cochlear nerve. The cochlear nerve carries impulses from the spiral cochlea and is therefore the nerve of hearing, while the vestibular nerve serves equilibrium, carrying impulses from the semicircular canals, utricle, and saccule.
* * *nervus vestibulocochlearis.
