The mandible is sub-divided into several other parts. These are:
The body of the mandible is the U-shaped section in the middle where the bottom teeth reside.
The ascending ramis is the flat portion connected to the body that reaches upward toward the skull.
The condyle and the coronoid process attach the ascending ramis to the skull. The condyle is the rounded end that fits into the joint, while the coronoid process is a projection that attaches to the chewing muscles of the jaw.
