A very large cord which was at first mistaken for a duct. that the cancellous bone of the process is richly supplied withbloodvessels, and the anastomosis with the vessels of themembrane, from the alveolar wall and over the border ofthe process, is important in the consideration of pathologicconditions. In alveolar abscess the vessels entering throughthe apical space may be entirely cut off, but this does notdisturb the blood supply of the rest of the membrane.
