Arterial Supply of the Guinea Pig Mandible

¹ Department of Anatomy, University of Michigan, Ann Arbor, Michigan

By the use of various injection technics and by dissection, it has been shown that the vessels supplying the condyle, coronoid process, and mandibular angle in the guinea pig arose from branches that supply the muscles attached to these processes and not from the inferior alveolar artery. The inferior alveolar artery tends to limit its region of supply to the body of the mandible, teeth, and periodontium. The mandible, like most of the other bones of the body, has a regional supply with the bony processes supplied by vessels that, in general, follow the muscles to their regions of insertion in the mandible.
