Theappearance is shown in Plate XVI and Figs. 245 and 246. BLOODVESSELS 313 Bloodvessels.—The peridental membrane possesses a veryrich blood supply. A number of vessels enter the membranein the apical portion from the medullary spaces in the bone. Fig. 242. Cm Transverse section, showing the cellular elements: Fb, fibroblasts; Ec, epithelialstructures; Cb, cementoblasts; Cm, cementum; D, dentine. (About 900 X) Some of these, passing through canals in the apex of the root,supply the dental pulp, others pass up through the mem-brane. As they extend occlusally they give off and receivebranches which enter the membrane from the bone of the 314 THE PERIDENTAL MEMBRAXE alveolar wall. In this way the caliber of the principal vesselsis maintained throughout their course in the membrane. Asthey reach the border of the alveolar process they give off Fig. 243
