Jaw Lower

**The lower jaw** is one of the two bones of the facial part of the skull, which participates in the formation of the lower jaw and acts as its support. One bone, the upper jaw, passes through the cranial vault and continues downward and outward in it; the other, the lower jaw, has its own continuous line of transverse sutures that separate its body from the body of the upper jaw. Each jaw is connected to the opposite skull by a fixed temporomandibular joint.
