Levator anguli oris

  • The levator anguli oris (also levator anguli oris muscle, latin: musculus levator anguli oris) is a facial muscle close to the mouth opening that lifts the angle of the mouth.

    The levator anguli oris originates from the canine fossa on the maxilla and inserts into the skin of the angle of the mouth.

    Upon contraction the levator anguli oris lifts the angle of the mouth. Contractions of this muscle produce a facial expression of self-confidence.

    The levator anguli oris is innervated by the buccal branch of the facial nerve (CN VII).
