The inferior alveolar nerve arises by a common trunk with the mylo-hyoid; it gives off dental branches and termmates m mental and inferior labial branches. The lingual nerve supplies vaso-dilator and excito-secretory filaments to the mandibular and sublingual salivary glands; these fibers are derived from the chorda tympani. The facial nerve divides near the posterior border of the jaw into four branches. The upper branch is the auriculo-palpebral nerve, which divides after a very short course into anterior auricular and zygomatic branches. The latter curves upward and forward across the zygomatic arch toward the eye, and divides into branches which supply the eyelids and nasal region and concur with the frontal and lacrimal nerves in forming the anterior auricular plexus. The superior buccal nerve ac- companies the parotid duct across the masseter. The inferior buccal nerve runs forward along the lower border of the masseter and the mandible. The two nerves.
