Mandibular Nerve or Third Division of Trigeminal nerve

This division supplies sensation to the mandible and the teeth. It contains somatic motor fibers as well as sensory nerve fibers. (The first two divisions are primarily sensory.) This nerve passes downward to enter the mandible through the mandibular foramen. Before entering the foramen, it gives off branches to the

  • muscles of mastication and
  • a large sensory branch to the tongue.

Thus, it provides motor impulses for mastication and general sensation to the

  • anterior two thirds of the tongue,
  • the mandible and
  • the mandibular teeth,
  • the soft tissues of the tongue,
  • the soft tissues of the floor of the mouth, and
  • the soft tissues surrounding the teeth.
