Further Studies into the Vascular Architecture of the Mandible

¹ Institute of Clinical Research, Middlesex Hospital, London, England

In this investigation warm carmine gelatin was injected via one common carotid artery, to demonstrate the vascular architecture of the mandible in adult cats. The histologic appearance of sections of cat mandibles is described. The author considers the inferior dental artery of each side to be the principal nutrient artery of the mandible. The lower border of the mandible is supplied by the arteries of the periosteum. An anastomosis exists between the inferior dental artery and the periosteal system of blood vessels. In the cat mandible an extensive capillary network connects the arteries with the veins. The blood supply of the mandible is compared with that of a long bone, and the relevant literature is discussed.
