Inferior Alveolar Nerve

The Inferior Alveolar nerve contains sensory fibers for the teeth of the mandible and their buccal gingiva, for the mucosa of the lower lip and for the skin of the lower lip and chin. It also contains motor fibers for the muscles of the floor of the mouth. The mylohyoid branch arises from the inferior alveolar nerve before the nerve trunk enters the mandibular canal. The mylohyoid nerve innervates the mylohyoid and the anterior digastric.
