Question

Quizplus · Accepted Answer

The hypoglossal nerve (cranial nerve XII) is responsible for motor function to the tongue, including tongue movement and speech. The glossopharyngeal nerve (cranial nerve IX) innervates the tongue for sensory function, while the facial nerve (cranial nerve VII) is responsible for facial muscle movement and sensation. The trigeminal nerve (cranial nerve V) is involved in sensation of the face and chewing muscles, but does not directly innervate the tongue.
