  • The first branch controls sensation in the eye, upper eyelid and forehead.

  • The second branch controls sensation in the lower eyelid, cheek, nostril, upper lip and upper gum.

  • The third branch controls sensations in the jaw, lower lip, lower gum and some of the muscles used for chewing.
