Trigeminal Nerve Distribution

The trigeminal nerve carries sensation from the face to the brain. The nerve has three branches:

• 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.
