The shoulder girdle consists of three bones - the clavicle, scapula, and humerus. It has several joints that provide a wide range of motion, including the sternoclavicular joint between the clavicle and sternum, the acromioclavicular joint between the clavicle and acromion, and the glenohumeral joint between the humerus and scapula. Numerous muscles attach to the shoulder bones including the deltoid, rotator cuff muscles, and latissimus dorsi, allowing movements like abduction, flexion, and rotation.
