  1. The muscle that is located superior to the rhomboid minor and elevates the scapula is the:
    levator scapulae
  2. The muscles that depress and protacts the shoulders and articulate anteriorly with ribs 3-5 are the:
    pectoralis minor
  3. This larger, and more inferior, muscle adducts the scapula and performs downward rotation.
    rhomboid major
  4. This smaller and more superior muscle adducts the scapula and performs downward rotation.
    rhomboid minor
  5. Which muscles protract the shoulder and performs upward rotation, articulating anteriorly with ribs 1-8?
    serratus anterior
  6. The muscle that depresses and protracts the shoulder and articulates with the clavicle and rib 1 is the:
    subclavius
  7. The large muscle connecting the occipital bone with the spinous processes of thoracic vertebrae which can elevate, retract, depress, or rotate the scapula is the:
    trapezius
  8. The muscle that provides for abduction of the arm at the shoulder as well as medial and lateral rotation of the arm is the:
    deltoid
  9. List the four muscles that make up the "rotator cuff."
    • supraspinatus
    • subscapularis
    • infraspinatus
    • teres minor
  10. The part of the rotator cuff allows for abduction of the arm at the shoulder.
    supraspinatus
  11. The muscle is located on the anterior side of the scapula and provides for medial rotation of the arm at the shoulder.
    subscapularis
  12. This muscle of the rotator cuff allows for lateral rotation of the arm at the shoulder.
    infraspinatus
  13. This muscle, located beneath the infraspinatus, which articulates with the lateral border of the scapula in order to facilitate lateral rotation of the arm is the:
    teres minor
  14. This muscle allows for the extension, adduction, and medial rotation of the shoulder and originates from the inferior angle of the scapula.
    teres major
  15. This muscle, which lies underneath the bicep, allows for the adduction and flexion at the shoulder and originates at the coracoid process of the scapula.
    coracobrachialis
  16. This anterior muscle, which articulates with the body of the sternum, provides for flexion, adduction, and medial rotation at the shoulder.
    pectoralis major
  17. This large muscle which articulates with the spinous processes of inferior thoracic and all lumbar vertebrae and allows for the extension, adduction, and medial rotation of the shoulder is the:
    latissimus dorsi
  18. List the three muscles that are arm flexors.
    • biceps brachii
    • brachialis
    • brachioradialis
  19. This "double-headed" muscle originates from the scapula and runs down the anterior surface of the humerous and facilitates flexion at the elbow and shoulder.
    biceps brachii
  20. This muscle, located underneath the bicep of the distal end of the humerous, facilitates flexion at the elbow.
    brachialis
  21. This muscle that runs along the anterior-lateral surface of the radius and allows for flexion at the elbow is the:
    brachioradialis
  22. The "three-headed" muscle that allows for the extension of the arm at the elbow is the:
    triceps brachii
  23. This muscle originates at the medial epicondyle of the humerous and connects to the midlateral surface of the radius and facilitates pronation.
    pronator teres
  24. This muscle originates at the lateral epicondyle of the humerous and is the antagonistic partner of the pronator teres.
    supinator
  25. List the three muscles of the superficial flexor compartment, which originate at the medial epicondyle of the humerus, and allow for flexion at the wrist.
    • flexor carpi ulnaris
    • palmaris longus
    • flexor carpi radialis
  26. This muscle originates at the lateral epicondyle of the humerus and allows for extension and adduction at the wrist.
    extensor carpi ulnaris
  27. The muscle that originates at the lateral epicondyle of the humerous and terminates on the posterior surface of phalanges 2-5 and allows for extension at the fingers joints and wrist is the:
    extensor digitorum
  28. The muscle, located underneath the three superficial flexor compartment muscles, that originates at the medial epicondyle of the humerus and terminates on the anterior surface of the middle phanlanges and allows for flexion of the joints in the hand is the:
    flexor digitorum superficialis
  29. Which of the three superficial compartment muscles is the most medial?
    flexor carpi ulnaris
  30. Which of the three superficial compartment muscles is in the middle?
    palmaris longus
