Sternoclavicular articulation. Anterior view.

Sternoclavicular articulation visible near center but not labeled.
Latin	articulatio sternoclavicularis

The sternoclavicular articulation is a double arthrodial joint. The parts entering into its formation are the sternal end of the clavicle, the upper and lateral part of the manubrium sterni, and the cartilage of the first rib, visible from the outside as the suprasternal notch. The articular surface of the clavicle is much larger than that of the sternum, and is invested with a layer of cartilage, which is considerably thicker than that on the latter bone.

The ligaments of this joint are:

The manubrium (from Latin manubrĭum, "a handle") or manubrium sterni is the broad, upper part of the sternum. With a quadrangular shape, wider superiorly and narrower inferiorly, it articulates with the clavicles and the first two ribs.
