From buccinare, 'to sound the trumpet.' The Buccina'tor Muscle, Retrac'tor An'guti Oris, Bucco-Alveolo-maxillaire, Alveolo-labial- (Ch.), Manso'rius, is situate in the substance of the cheeks. It extends between the posterior portions of the alveolar arches of the two jaws and the commissure of the lips, which it draws backward. It assists in mastication, by pushing the food back towards the teeth; and, if the cheeks be distended by air, its contraction forces it out.
