Lingual Nerve Anatomy

The lingual nerve is a branch of the mandibular division of the trigeminal nerve which supplies general sensory innervation to the anterior 23 of the tongue. Anatomy of the lingual nerve the lingual nerve is a branch of the mandibular division of the trigeminal nerve supplying the anterior two thirds of the tongue and responding to stimuli of pressure touch and temperature image 1 2.

Trigeminal Nerve

It also carries fibers from the facial nerve which carries taste information from the anterior two thirds of the tongue via the chorda tympani.

Lingual nerve anatomy. The lingual nerve branches off from the mandibular jaw division of the trigeminal nerve. The lingual nerve is a sensory branch of the posterior division of the mandibular division of the trigeminal nerve. It supplies feeling to the floor of your mouth and the front two thirds of the tongue.

It branches off the mandibular nerve and twists around the submandibular duct to reach the tongue. The lingual nerve divides off the posterior division and descends anterior to the inferior alveolar nerve to course between the lateral pterygoid and tensor veli palatini muscles and then medial pterygoid muscle and the mandible contacting the internal surface of the mandible at the posterior margin of the mylohyoid line. The facial nerves chorda tympani is one of the nerve fibers the lingual nerve carries to the skull.

It supplies feeling to the floor of your mouth and the front two thirds of the tongue. The lingual nerve provides senses to the tongues front two thirds as well as to the underside that surrounds it. The lingual nerve is often in a common stem with the inferior alveolar nerve after the mandibular division enters the infratemporal fossa through foramen ovale1 the lingual nerve separates from the inferior alveolar nerve and then descends anteriorly into the oral cavity.
