VIII nerve receives afferents of (AIIMS MAY 2011)



A Taste

B Balance

C Hearing

D Equilibrium

Ans. C Hearing

a. The vestibulocochlear nerve (also known as the auditory or acoustic nerve) is the eighth cranial nerves, and is responsible for transmitting sound and equilibrium (balance) information from the inner ear to the brain.

b. This is the nerve along which the sensory cells (the hair cells) of the inner ear transmit information to the brain. It consists of the cochlear nerve, carrying information about hearing, and the vestibular nerve, carrying information about balance.

c. Some older texts call the nerve the acoustic or auditory nerve, but these terms have fallen out of widespread use because they fail to recognize the nerve's role in the vestibular system, Vestibulocochlear nerve is therefore preferred by most.

d. So, options B,C & D all are correct as far as function of VIII Nerve is concerned, but the best would be C i.e. Hearing as Balance & Equilibrium are same functions.
