Diagram of the trigeminal nerve. From An Atlas of Anatomy by John Charles Boileu Grant, 1962. The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the largest of the cranial nerves. The three major branches of the trigeminal nerve???the ophthalmic nerve (V1), the maxillary nerve (V2) and the mandibular nerve (V3)???converge on the trigeminal ganglion (also called the semilunar ganglion or gasserian ganglion), located within Meckel's cave and containing the cell bodies of incoming sensory-nerve fibers.
