The mental nerve is a sensory nerve of the face. It is a branch of the posterior trunk of the inferior alveolar nerve, itself a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). It provides sensation to the front of the chin and the lower lip, as well as the gums of the anterior
The inferior alveolar nerves supply sensation to the lower teeth, [2]: 519 and, via the mental nerve, sensation to the chin and lower lip. [citation needed] The mylohyoid nerve is a motor nerve supplying the mylohyoid and the anterior belly of the digastric. [citation needed] [contradictory]
It provides motor innervation to muscles of the lower lip and chin: the depressor labii inferioris muscle, depressor anguli oris muscle, and mentalis muscle. [1] It communicates with the mental branch of the inferior alveolar nerve. [citation needed]
Bilateral facial nerve paralysis may occur in Guillain–Barré syndrome, an autoimmune condition of the peripheral nervous system. [6] Moebius syndrome is a bilateral facial paralysis resulting from the underdevelopment of the VII cranial nerve (facial nerve), which is present at birth. The VI cranial nerve, which controls lateral eye movement ...
Unlike the other divisions of the trigeminal nerve (ophthalmic nerve, maxillary nerve) which contain only afferent fibers, the mandibular nerve contains both afferent and efferent fibers. These nerve fibers innervate structures of the lower jaw and face, such as the tongue , lower lip , and chin .
Existing treatments aim to suppress the immune system to prevent further damage to nerve cells. A new study has developed a treatment that can help regenerate myelin with the potential to stop and ...
The mandibular nerve (V 3) carries sensory information from the lower lip, the lower teeth and gums, the chin and jaw (except the angle of the jaw, which is supplied by C2-C3), parts of the external ear and parts of the meninges. The mandibular nerve carries touch-position and pain-temperature sensations from the mouth.
The buccal branches of the facial nerve (infraorbital branches), are of larger size than the rest of the branches, pass horizontally forward to be distributed below the orbit and around the mouth. Branches
