Trigeminal Nerve

The "trigeminal nerve" refers to either of the 5th pair of cranial nerves. These nerves in the head are involved in giving feeling and movement to the face, teeth, mouth and nasal cavity. The trigeminal nerve relays pain messages, and may play a key role in migraine by causing inflammation.
