The document discusses the anatomy of the temporomandibular joint (TMJ), which connects the mandible to the temporal bone of the skull. It describes the bones that make up the joint, including the mandibular condyle and fossa, as well as the ligaments and muscles involved. The articular disc and how it functions within the joint is also examined. A number of images are provided to illustrate the osteology and structural components of the TMJ.

3. Introduction
The temporomandibular joint is the joint of the jaw and is frequently referred to as
TMJ,Is a bilateral synovial bicondylar articulation between the mandible and
temporal bone (skull), Regulates mandibular movement.
