Answers
Jaw, either of a pair of bones that form the framework of the mouth of vertebrate animals, usually containing teeth and including a movable lower jaw (mandible) and fixed upper jaw (maxilla). ... Jaws function by moving in opposition to each other and are used for biting, chewing, and the handling of food.
The lower jaw (mandible) supports the bottom row of teeth and gives shape to the lower face and chin. This is the bone that moves as the mouth opens and closes. The upper jaw (maxilla) holds the upper teeth, shapes the middle of the face, and supports the nose.

The left and right halves of the lower jaw, or mandible, begin originally as two distinct bones, but in the second year of life the two bones fuse at the midline to form one. The horizontal central part on each side is the body of the mandible
Located on each side of the head, they work together to make many different movements, including a combination of rotating and gliding actions used when chewing and speaking. Several muscles also help open and close the mouth. They control the lower jaw (mandible) as it moves forward, backward, and side-to-side.
