The Trigeminal Nerve (Cranial Nerve V)

The trigeminal nerve, or fifth cranial nerve, is responsible for sensation in the face as well as chewing and biting[1]. This nerve originates on the pons, which is part of the brainstem[2]. It splits into three separate nerves; the ophthalmic, the maxillary, and the mandibular nerve[1]. The main functions are to receive sensation from the face, and control the four main muscles required for chewing[2].
