shoulder is made up of three bones—the clavicle,
scapula, and humerus—held together by muscles, tendons, ligaments, and a joint
The collarbone (clavicle) attaches the shoulder
to the breastbone (sternum). It connects with the large, flat, triangular
shoulder blade (scapula) at its upper, outer corner (acromion).
acromion extends from the scapula to form the roof of the shoulder. It lies
above the shoulder socket, called the glenoid fossa. The top (head) of the
upper arm bone (humerus) is cradled in this socket, forming the shoulder joint

and their related muscles—the supraspinatus, infraspinatus, subscapularis, and
teres minor—that stabilize the shoulder joint and allow raising and rotating of
