The Mandible.—The mandible (Fig. 2) is a horseshoe-shaped bone, and consists of a horizontal portion calledthe body, and two rami. The body extends in a curvedmanner on either side of the median line, and joins eachramus at about a right angle. The ramus is surmountedby two processes—the coronoid process in front, for the BONES 23 insertion of the temporal muscle, and the condyloidprocess behind, the tip of which articulates with theanterior portion of the glenoid fossa of the temporalbone, forming the temporomandibular joint.
