Describe the structure and movements of the TMJ
The temporomandibular joint (TMJ) is a hinge joint that connects our jaw to the temporal bones of our skull, which are in front of each ear. It lets us move our jaw up and down and side to side, so we are able to talk, chew, and yawn. It is formed by the articulation of the mandible and the temporal bone of the cranium. It is found anteriorly on the lateral aspect of the face. There are also other conditions or defects that may lead to the development of TMJD (disorder) that may cause arthritis, joint erosion, grinding or clenching of the teeth, structural jaw problems present at birth and so on. The problems associated with jaw and the muscles in our face that control it are known as temporomandibular joint (TMD).
