. Anatomy, descriptive and applied. Anatomy. Fig. 929.—Right half of upper jaw (from below), with the corresponding teeth. The letters and numbers point to the classes of teeth and the numbers in classes. Fig. 930.—Right half of lower jaw. with the cor- responding teeth. The letter and numbers point to the various cusps or their modifications on the differ- ent teeth. (Burchard.) The incisors of the upper jaw are altogether larger and stronger than those of . the lower jaw, the central incisors being larger and flatter than the lateral incisors. They are directed obliquely downward and forward. The incisors of the lower jaw are smaller and flatter than the upper, and the elevations upon their lingual faces are not marked. The two central are smaller than the two lateral incisors, being the smallest of all the teeth. The roots of these teeth are flattened laterally. The Canine Teeth {denies canini) are four in number, two in the upper, two in the lower jaw—one being placed distal to each lateral incisor. They are larger and stronger than the incisors, especially in the roots, which are deeply implanted and each causes a well-marked prominence of the process at the place of inser- tion. The crown is large, of spear-head form, and its very convex labial surface is marked by three longitudinal ridges. The concave lingual surface is also marked by three ridges which unite at a basal ridge. The point or cusp is longer than in the other teeth, and is the point of division between a short proximal and a long distal cutting edge. These two edges form an obtuse angle with each Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray, Henry, 1825-1861; Spitzka, Edward Anthony, 1876-1922.
