Articular disk of sternoclavicular articulation
|Articular disc of sternoclavicular articulation|
Sternoclavicular articulation. Anterior view. (Articular disk labeled at upper right.)
|Latin||Discus articularis articulationis sternoclavicularis|
It is attached, above, to the upper and posterior border of the articular surface of the clavicle; below, to the cartilage of the first rib, near its junction with the sternum; and by its circumference to the interclavicular and anterior and posterior sternoclavicular ligaments.
It is thicker at the circumference, especially its upper and back part, than at its center.
It divides the joint into two cavities, each of which is furnished with a synovial membrane.
