A text-book of dental histology and embryology, including laboratory directions . Diagram of peridental membrane from section similar to Fig. 224. (From Maloc-clusion of the Teeth, Dr. E. H. Angle.) Fig. 226. Fibers at the border of the alveolar process (from sheep): D, dentine; C,cementum; F, fibers extending from cementum to bone; Bl, bloodvessel; B, bone.(About 80 X) ARRANGEMENT 293 of the alveolar portion from the incisor of a sheep. Uponthe labial a few muscle fibers are seen and the periosteumcovering the labial surface of the process. Notice the medul-lary spaces in the bone and the canals opening into theperidental membrane and periosteum. The light line formingthe outer boundary of the dentine is characteristic. Twolayers of cementum are seen, and notice the thickening of thelayer where strong bundles are attached. At the middle ofthe labial surface the fibers pass at right angles to the cemen-tum and are attached to the bone, but as the distolabialangle of the root is approached the bundles swing distally tobe attached in the bone. In Fig. 225, which was drawn verycarefully from this section, the arrangement of the fibers isshown diagrammatically. Notice the way in which theypa
