The term MANDIBLE SITE refers to the JAW, which is a hinged joint in the skull that allows for movement of the lower JAW. It is composed of two bones, the mandible and the maxilla, which are connected by muscles and ligaments. The mandible is the lower jawbone and is the only movable bone in the face. It is responsible for chewing, speaking, and facial expressions. The mandible site is the point where the mandible attaches to the skull.
