Often asked: How Your Jaw Bone Works Anatomy?

How does a jaw bone work?

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.

What are the parts of the jaw?

It consists of two main parts. The upper part is the maxilla. It doesn’t move. The moveable lower part is called the mandible.

How does the human jaw move?

In mastication in humans, the hyoid moves upward and forward during jaw opening and in the opposite direction during closing (Pancherz, Winnberg and Westesson, 1986). The movement during opening is presumably a result of the attachment of the supra- hyoid muscles to both the hyoid and the mandible.

What is the lower jaw bone called?

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.

What is your jaw muscle called?
