The fifth cranial nerve, known as the trigeminal nerve (V), is the largest of the twelve cranial nerves and carries both sensory and motor fibers.[1] It has three terminal branches, which in descending order are ophthalmic nerve (V1), maxillary nerve (V2), and mandibular nerve (V3). The ophthalmic and maxillary divisions carry only sensory fibers while the mandibular division carries both sensory and motor fibers. The intermediate division, maxillary nerve (V2), primarily supplies sensory innervation to the middle third of the face. It also carries postganglionic fibers from pterygopalatine ganglion which supply the lacrimal gland and mucous glands of the nasal mucosa.
