Where the clavicle sits in the skeleton

The clavicle is an S-shaped bone lying across the top of the chest to the shoulder. It joins the sternum at its inner end and the scapula at its outer end, linking the arm to the trunk. Its inner end meets the manubrium of the sternum and the first costal cartilage at the sternoclavicular joint, and its outer end meets the acromion of the scapula at the acromioclavicular joint. It is the first bone in the fetus to begin turning into bone.
