The temporomandibular joint (TMJ) is a bilateral synovial articulation between the ends of the mandible (lower jaw) and temporal bone, part of the skull. Both mastication and facial muscles are attached to the lower jaw. 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.

This joint is developed between the membrane which covers the condyle of the mandible and the periosteum of the squamosum. In the loose tissue between the two a condensation marks the beginning of the differentiation of the discus articularis. On each side of this discus a joint cavity develops. Each joint cavity is throughout life lined by fibrous tissue. Beneath the joint periosteum of the mandible and of the temporal bone a thin layer of cartilage is produced (see Kjellberg, 1904).
- according to Walliseh (1906), in the new-bom the tubereulum articulare is still undeveloped and the condyle is flatter than in the adult. The condyle reaches its definitive form and the tubereulum is developed after the teeth appear.
- according to Fuebs (1905), tbe temparomandibular joint in rabbits, and hence by inference in other mammals, is homologous with the quadra to-articular joint of reptiles. As mentioned above, following Reiehert, most investigators have come to the conclusion that the reptilian quadra to-articular joint is represented in mammals by tbe joint between the malleus and incus, while the temporomandibular joint of mammals is phylogenetieally a new structure, a squamosodental joint. (See Gaupp, 1906.)
