Based on the directional arrow in this standing shoulder movement/exercise, the shoulders are ____________ and the posterior deltoid, latissimus, and long head of triceps are likely performing ________________. a. abducting , no contraction b. extending , concentric contraction c. flexing, eccentric contraction d. internally rotating , no contraction 26. Based on the directional arrow in this seated shoulder movement/exercise, the shoulders are ____________ and the prime mover is likely the ________________. a. horizontally adducting , pectoralis major b. flexing , long head of biceps c. externally rotating , infraspinatus d. adducting , posterior deltoid e. horizontally abducting, pectoralis minor 27.

After the ball is released, the humerus of the pitching arm rotates and moves across the body, all at a high velocity (called “the follow through”). The prime movers for slowing the arm down after the ball is released are the a. internal rotators and horizontal adductors. b. external rotators and horizontal abductors. c. internal rotators and horizontal abductors. d. external rotators and horizontal adductors 31. At the glenohumeral joint, the factor LEAST responsible for maintaining joint stability is a. bony fit (bony congruency) b. capsule and ligaments c. rotator cuff 32. In goniometry, we use the medial epicondyle as a landmark for goniometric measurement of _______________. a. flexion b. extension c. internal rotation d. abduction 33. Arthrokinematics of SC joint protraction & retraction follows the rule of moving __________ surfaces. a. convex b. concave c. both convex and/or concave is correct because SC joint has a saddle shape 34.

According to Neumann, muscle paralysis that leads to a chronically and excessively depressed and downwardly rotated scapula may result in a. inferior dislocation of the SC joint. b. compression of nerves and blood vessels (ie. brachial plexus and subclavian artery) under the clavicle. c. superior subluxation/dislocation of the GH joint. d. an elevated distal end of the clavicle. e. two of the above. Note: A wide variety of additional questions could be formed about the movements shown in questions 19-21
and 24-26. Such things as 1) agonist (prime movers) and antagonists during each phase, 2) all obvious
scapular and glenohumeral movements during each phase, and 3) types of contractions occurring during each
phase . . . should be considered and analyzed.
