Anatomical terms of bone

The mandible is a bone found in all jawed vertebrates. The name comes from Latin mandibula.

In bony fish the lower jaw is made of a number of bones, but these were gradually reduced in evolution.

In humans and other mammals the mandible is simply the jawbone or dentary, which is the largest and strongest bone of the face.

In mammals bones formerly in the lower jaw have become the ear ossicles.
