Shoulder Blades

The shoulder blades, or scapulae, form part of the shoulder joint and rest on the back of the rib cage where they are connected to the body by several muscles. These muscles include: the serratus anterior, latissimus dorsi, rotator cuff muscles and trapezius muscles. The muscles work together to rotate the shoulder blades, allowing the upper extremities to move, and to provide stability for the shoulder joint and arms.
