The trigeminal nerve (the fifth cranial nerve or simply CN V) is a nerve responsible for sensation in the face and certain motor functions such as biting and chewing. It is the largest of the cranial nerves. Its name (trigeminal = tri- or three and -geminus or twin or thrice twinned) derives from the fact that each trigeminal nerve one on each side of the pons has three major branches: the ophthalmic nerve (V1) the maxillary nerve (V2) and the mandibular nerve (V3).
