The sensory nerves of the mouth descend from both the trigeminal nerve and more prominently from the facial nerve. The fibers of the mandibular division of the trigeminal nerve include sensory branches that transmit impulses from the skin of the jaw, the lower teeth, the lower gum, and the lower lip. Additionally, the facial nerve divides into smaller nerves that reach into the face, neck, salivary glands and the outer ear. These branches report taste sensations from the front two-thirds of the tongue.
