INTRODUCTION ANATOMY OF THE TRIGEMINAL NERVE The trigeminal nerve is composed of a large sensory division whose unipolar cells are in the Gasserian ganglion, and a small motor division distributed entirely through the mandibular branch of the nerve. The skin of the face and the mucous membrane of the mouth, tongue, and nose are supplied by pain, tactile, and thermal fibers which pass into all three branches of the trigeminal nerve;
