Detailed explanation-1: -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-2: -Evaluation of the vestibulocochlear nerve, therefore, involves testing of the hearing and balance. Otoscopic inspection of the auditory canals and tympanic membranes is done, as well as assessment of each ear’s auditory acuity. Weber and Rinne tests are performed using a 512-Hz tuning fork.

Detailed explanation-3: -Vestibular neuritis is a disorder that affects the vestibulocochlear nerve of your inner ear. This nerve sends information about your balance and head position from your inner ear to your brain. When this nerve becomes inflamed or swollen, it interrupts the way your brain reads information.

Detailed explanation-4: -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.
