Shoulder Girdle

Shoulder movements are composite, involving the ball and socket articulation at the shoulder (glenohumeral) joint, together with movements between the scapula and clavicle, and the thorax. The shoulder girdle muscles are detailed in tables 2&3, and figure 27 shows the muscles of the superior aspect of the shoulder.
