The trigeminal nerve is the largest and most complex of the 12 cranial nerves. The trigeminal nerve (the fifth cranial nerve) is a nerve responsible for sensation in the face and motor functions such as biting and chewing. Its name derives from the fact that each of the two nerves (one on each side of the pons) has three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3). The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory (or "cutaneous") functions.
