head of the humerus, Acromial end of the clavicle

Explanation:

The shoulder is made up of three bones: the scapula, the clavicle and the humerus (upper arm bone).  Two joints in the shoulder allow it to move: the  acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle at its acromial end (the sternal end of the clavicle is bounded to the sternon), and the glenohumeral joint. The scapula also bounds to the head of the humerus, it is, the distal superior end.
