The inferiorturbinated develops by a single centre, which appearsabout the fourth month. THE INFERIOR MAXILLARY. The inferior maxillary is an irregular bone whichforms the lower jaw. It is the strongest and largestbone of the face, and consists of a body and two body, placed horizontally, is bent like a horseshoe; it S^l^^. Fig. 25.—Inferior maxillary Bone, is a thick plate of bone, curved on the flat, and presentsfor examination an external and internal surface, asuperior and inferior border. The external surface isstrongly convex from side to side, and, in front, concavefrom above downward. It is somewhat rough andirregular, and presents in the median line a ridge, whichindicates the line of union (symphysis) between the twohalves of the bone. This ridge expands near the inferiorborder in a triangular, slightly-elevated mass of bone,—the mental process. On each side of the ridge, beneaththe incisor teeth, is a shallow depression, the incisivefossa, which gives origin to the levator menti muscle. THE INFERIOR MAXILLARY. 55 External is the canine eminence, which marks theposition of the root of the canine tooth; it is less devel-oped than the canine eminence of the upper an inch and a quarter external to the median lin
