Question

The semicircular canals of the inner ear are innervated by the _______ nerve.
A) vestibulocochlear
B) vagus
C) trigeminal
D) hypoglossal

Accepted Answer

The vestibulocochlear nerve (CN VIII) is responsible for transmitting sensory information from the vestibular system, which includes the semicircular canals, to the brainstem. It plays a crucial role in balance and spatial orientation. The vagus nerve (CN X) innervates various organs in the body, while the trigeminal nerve (CN V) deals with sensation in the face and oral cavity, and the hypoglossal nerve (CN XII) controls tongue movement.
