Anatomical terms of muscle

The levator anguli oris (caninus) is a facial muscle of the mouth arising from the canine fossa, immediately below the infraorbital foramen.

Its fibers are inserted into the angle of the mouth, intermingling with those of the Zygomaticus, Triangularis, and Orbicularis oris. Specifically, the levator anguli oris is innervated by the buccal branches of the facial nerve.
