Sternal head: sternum, upper costal cartilages (1-6), and the aponeurosis of the external oblique. The clavicle articulates with the acromion at the acromioclavicular joint laterally and the sternum at the sternoclavicular joint medially. The clavicle is a doubly-curved long bone (the only horizontal long bone in the human body) that connects the arm to the body (), located directly above the first rib.Medially, it articulates with the manubrium of the sternum (breast-bone) at the sternoclavicular joint.At its lateral end it articulates with the acromion of the scapula (shoulder blade) at the acromioclavicular joint. The clavicle is thicker and more curved in manual workers, and the sites of muscular attachments are more marked. It is worth noting that subclavius is the only muscle that has its main attachment in the middle third of the clavicle.
