Question

which cranial nerve carries hearing and equilibrium sensory information to the brain?
a vestibulocochlear
b facial
c trigeminal
d auditory

Explanation:

• The vestibulocochlear nerve (cranial nerve VIII) is responsible for transmitting auditory (hearing) and vestibular (equilibrium) sensory information to the brain.
• The facial nerve (cranial nerve VII) is mainly involved in facial expression, taste (anterior two - thirds of the tongue), and salivation.
• The trigeminal nerve (cranial nerve V) is associated with sensory functions (touch, pain, temperature) from the face and motor functions for chewing.
• There is no cranial nerve named "auditory" as a separate cranial nerve; the vestibulocochlear nerve has the auditory component.

Answer:

A. vestibulocochlear
