The Temporomandibular Joint (TMJ) is a bilateral synovial articulation between the ends of the mandible (lower jaw) and temporal bone ( part of the skull).
The earliest review of human embryonic and fetal TMJ development is by Symons in 1952.
In the adult, the region where two skeletal bones meet and articulate is called a "joint", that are classified based upon their: anatomical structure, mobility and shape. In the embryo, the majority of the vertebrate skeleton is initially formed as a cartilage template, that is later replaced by bone except at the interface between two adjacent bones, leaving in the adult a layer of cartilage in this region. The musculoskeletal system consists of skeletal muscle, bone, and cartilage and is mainly mesoderm in origin with some neural crest contribution.
