Trigeminal Nerve (CN V)

Target
CN V
Molecular classification
Nerve, Cranial Nerve
01

Overview

The trigeminal nerve (CN V) is the largest cranial nerve, responsible for sensory innervation of the face and motor innervation of the muscles of mastication. It has three main branches: ophthalmic (V1), maxillary (V2), and mandibular (V3). Disorders involving the trigeminal nerve include trigeminal neuralgia, characterized by severe facial pain, and facial paralysis or sensory loss due to injury or disease.

Other names
Fifth Cranial Nerve
