What does the trigeminal nerve do?

ANSWER

It splits into three branches which control the feeling for different parts of your face.

The ophthalmic branch controls your eye, upper eyelid, and forehead. The maxillary branch affects your lower eyelid, cheek, nostril, upper lip, and upper gum. The mandibular branch runs your jaw, lower lip, lower gum, and some of the muscles you use for chewing.
