Sample Questions What the the correct and specific name of the shoulder joint? Glenohumeral joint What muscle works closely with the anterior deltoid? Pectoralis major What action does the pectoralis minor and serratus anterior have in common? Abduction of the scapula Name the four rotator cuff muscles. Subscapularis, Supraspinatus, Infraspinatus, and Teres minor. Name a muscle that has as its actions both elevation and depression of the scapula? Trapezius
