Both fresh and fixed cadaver specimens are used to demonstrate the arterial blood supply to the muscles of the face and the temporomandibular joint. Specific perfusion of the internal maxillary artery demonstrates that there is ample blood supply from the posterior and lateral of the condyle as well as from the anterior region.
