Below are types of questions you might expect to see on exams
1. Which muscle(s) is (are) capable of producing upward/outward
rotation of the inferior angle of the scapula?
a. serratus anterior
b. tibialis anterior
c. serratus posterior
d. upper trapezius
e. a & b
f. a & c
g. a & d
2. Biceps brachii can:
a. flex the shoulder joint
b. flex the elbow joint
c. supinate the forearm
d. all of the above
e. none of the above
3. The motion(s) possible at the proximal radioulnar joint is
(are):
a. flexion/extension
b. protraction/retraction
c. supination/pronation
d. inversion/eversion
e. b & d
4. Where would a lesion of the brachial artery have to occur
to obliterate the radial and ulnar arterial pulses?
a. at the midshaft level of radius
b. just proximal to the medial epicondyle of humerus
c. at the midshaft level of humerus
d. at the radial styloid process
e. b or c
5. A bullet has lodged in the axilla of a man following a gun
battle with the police. The bullet struck a bone, shattered,
and completely severed the posterior cord of the brachial
plexus. Which muscle(s) would not be affected by this
injury?
a. latissimus dorsi
b. subscapularis
c. triceps brachii
d. extensor carpi radialis brevis
e. serratus anterior
f. all of the above would be affected
6. A patient reports she has just fallen off a step-stool and
landed directly on her left shoulder. She reports numbness
directly over the glenohumeral joint. She is unable to flex nor
abduct his shoulder. On manual muscle test external rotation of
the shoulder is weakened. The extensors of the arm and forearm
are also paralysed. X-ray show a posterior dislocation of the
glenohuermal joint. Which stucture has been injured?
a. axillary nerve
b. supraspinous nerve
c. radial nerve at the deltoid tubercle
d. posterior cord of the brachial plexus
e. long thoracic nerve
f. medial cord of the brachial plexus
True/False/Related
Each phrase below is separated by the word BECAUSE. Decide whether each phrase is true or false If both are true, decide whether there is a justifiable relationship between them. If a relationship exists, place a "1" in the blank on the answer sheet: (True/True/Related). If no relationship exists, place a "2" in the blank: (True/True/Unrelated). If one or both of the phrasesis (are) false, select the appropriate combination of choices from "3" to "5". Remember if one or both phrases is (are) false you assume no relationship exists and your asnwer must be from choices "3" to "5".
1 True/True/Related
2 True/True/Unrelated
3 True/False
4 False/True
5 False/False
7. A patient with complete transection of the posterior cord of the brachial plexus may be able to flex the elbow BECAUSE the triceps brachii is innervated by the radial nerve.
8. Coracobrachialis is a shoulder joint extensor BECAUSE its line-of-action is posterior to the axis for flexion/extension.
