They move in consent with the muscles of respiration. Muscles of the lips : — : F. Levator Labii Proprius. It arises from the upper jaw-bone, near the orbit, and is inserted into the upper lip, which it raises. c. Levator Anguli Oris. This muscle, lying under the last, is, of course, shorter: it raises the angle of the mouth. H. Zygomatic Muscle. So called, because its origin is from the zygomatic process of the cheek-bone. It is inserted into the angle of the mouth. k. Orbicularis Muscle of the Lips. M. Nasalis Labii Superioris. Draws down the septum of the nose. N. Triangularis Oris, or Depressor Labiorum. A strong muscle arising from the base of the lower jaw, and inserted into the angle of the mouth. Quadratus Menti, or Depressor of the Lower Lip. . Levatores Menti. Small, but strong, muscles. They arise from the lower jaw near the alveolar processes of the incisor teeth, descend, and are inserted into the integument of the chin. By their action they throw up the chin and project the lower lip. qa. The Buccinator forms the fleshy part of the cheeks. It acts principally in turning the morsel in the mouth. Its fibres are inserted into the angles of the mouth. . Fibres of the Platysma Myoides, which ascend from the neck upon the side of the cheek. sec Ps]](https://iiif.wellcomecollection.org/image/b33522133_0284.jp2/full/800%2C/0/default.jpg)
