Detailed explanation-1: -The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain.

Detailed explanation-2: -The vestibulocochlear nerve consists of the vestibular and cochlear nerves, also known as cranial nerve eight (CN VIII). Each nerve has distinct nuclei within the brainstem. The vestibular nerve is primarily responsible for maintaining body balance and eye movements, while the cochlear nerve is responsible for hearing.

Detailed explanation-3: -The vestibulocochlear nerve is the eighth cranial nerve. Its cochlear branch is responsible for the special sensation of hearing, and its vestibular portions are involved in balance, spatial sensation, and posture.

Detailed explanation-4: -The auditory nerve divides into two branches: the cochlear nerve and the vestibular nerve. The former receives auditory information from the inner ear. The latter receives information about balance. When the auditory nerve is damaged, the primary symptoms are sensorineural deafness and/or vertigo.

Detailed explanation-5: -The vestibulocochlear nerve provides for hearing and balance. Patients with this nerve injury oftentimes have vertigo, tinnitus, and hearing impairment. Hearing loss due to TBIs is more frequently a sensory loss than a conductive loss. Patients may often complain of the sensation of the room spinning around them.
