The structural component of an animal skeleton where two or more skeletal elements meet, including the supporting structures within and surrounding it. Anatomically, a joint (also known as an articulation) is a contact surface between two individual bones (Fig. 1). The relative range of motion between the skeletal elements of a joint depends on the type of material between these elements, the shapes of the contacting surfaces, and the configuration of the supporting structures. In addition, local or generalized disturbances that affect joints and related tissues are common conditions. The most common conditions are forms of arthritis, which cause the inflammation or degeneration of joint structures.
