It lines every part of the alveoli, and, passing over thegingival margins, is continuous with the periosteum and gumscovering the outer plate of the alveolar process. It is onemembrane, attached on one side to the root of the tooth, andon the other to the inner wall of the alveolus. It is composedof connective tissue which supports an abundant supply ofblood-vessels, nerves and lymphatics. With these are inter-mingled strong fibres of white fibrous tissue which pass fromthe cementum of the root of the tooth to the bony walls of the. Fig. 140.—Actual size.
