•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
Sample Questions
• List the muscles that do flexion of the shoulder
• Coracobrachialis• Pectoralis major
(upper to 60°)• Anterior Deltoid
• List the muscles that do extension of the shoulder
• Latissimus dorsi• Teres major• Posterior deltoid• Pectoralis major
(lower fibers to neutral)
