[Dilates anterior nares.] SUPERIOR MAXILLARY REGION. Levator labii superioris : superior maxilla and malar above infra-orbital foramen(F)—orbicularis oris(F) (Facial). [Raises upper lip.] Levator anguli oris: canine fossa of superior maxilla, beneath infra-orbital foramen(F)—angle of mouth(F) (Facial). [Raises angle of mouth, as in smiling.] Zygomaticus major: malar bone in front of zygoma(F)— angle of mouth(F) (Facial). [Raises angle of mouth.] Zygomaticus minor: malar bone near maxillary suture(F) —angle of mouth(F) (Facial). [Raises angle of mouth.] INFERIOR MAXILLARY REGION. Levator labii inferioris, vel levator menti: incisor fossa of inferior maxilla(F)—integument of chin(F) (Facial). [Raises skin of chin.] Depressor labii inferioris, vel quadratus menti: external oblique line of inferior maxilla from symphysis to mental foramen(F)—orbicularis oris(F) (Facial). [Draws down lower lip, everting it.] Depressor anguli oris, vel triangularis menti: external oblique line of inferior maxilla(F)—angle of mouth(F) (Facial). [Depresses angle of mouth, as in crying.] X INTER-MAXILLARY REGION, ■^' Orbicularis oris : sphincter of mouth. The labial part is free from attachment to bone, and forms red part of lips. The outer or facial part is connected with the muscles which converge to the angles of the mouth, and is attached in the upper lip to septum nasi and incisive fossa of superior maxilla, and in the lower lip to canine fossa of inferior maxilla(F) (Facial). [Closes oral fissure, producing radiating wrinkles.] Buccinator: external surfaces of alveolar processes of superior and inferior maxillae, as far forwards as ist molar; pterygo-maxillary ligament(f)—angle of mouth where fibres decussate(f) (Facial).
