The jaw, also known as the mandible, is the largest and strongest bone in the human skull and plays a crucial role in various essential functions. The jaw is responsible for activities such as biting, chewing, and speaking. It serves as a framework for the lower teeth and provides support to the facial structures. The movement of the jaw is controlled by powerful muscles, allowing for precise and coordinated actions during eating and speaking. Additionally, the jaw contributes to the aesthetics of the face and plays a significant role in facial expressions and overall facial symmetry.
