Which bone is the jawbone, the moveable bone in the skull?

Explanation:
The movable jawbone is the mandible, the lower jaw. It houses the lower teeth and sits on the temporomandibular joint with the temporal bone, allowing the jaw to move for chewing and speaking. The maxilla is the fixed upper jaw, the temporal bone is part of the side of the skull (and forms part of the jaw joint), and the zygomatic bone is the cheekbone. The mandible is the only skull bone that moves substantially.
