Flexor pollicis longus D. 1st and 2nd lumbricals E. Adductor pollicis Q2 2. All of the following statements regarding the actions of the interosseous muscles are CORRECT EXCEPT: A. They abduct the digits B. They adduct the digits C. They extend at the interphalangeal joints D. They flex at the metacarpophalangeal joints E. They extend at the metacarpophalangeal joints Q3 3. Which of the following is INCORRECT regarding the erector spinae muscle: A. The muscle extends from the sacrum to the base of the skull B. The muscle is invested by two layers of the thoracolumbar fascia C. The major action of the muscle is to extend the vertebral column D. The erector spinae muscle is arranged in three vertical columns: rotatores; semispinalis; and multifidus E. The muscle is innervated by the dorsal rami of spinal nerves Q4 4. Choose the INCORRECT statement concerning the components of synovial joints: A. The synovial membrane does not cover the articular surfaces of a synovial joint. B. Articular cartilage often degenerates with aging or injury C. The fibrous joint capsule is anchored to articular cartilage D. The nerves which innervate the muscles acting upon a joint will also innervate the joint E. Synovial fluid not only lubricates articular surfaces but nourishes the articular cartilage Q5 5. Which of the following statements about the axillary artery or its major branches is INCORRECT: A. The thoracoacromial trunk supplies blood to the deltoid muscle B. The second part of the axillary artery lies posterior to the pectoralis minor muscle C. The lateral thoracic artery supplies blood to the breast D. The thoracodorsal artery is the major blood supply to the latissimus dorsi muscle E. The posterior circumflex humeral artery passes through the triangular space Q6 6. All of the following statements regarding the anatomical snuffbox are CORRECT EXCEPT: A. The scaphoid and trapezium form its floor B. The tendons of the abductor pollicis longus, extensor pollicis brevis and extensor pollicis longus form its boundaries C. The superficial radial nerve traverses this area D. The radial artery courses across its floor E. The extensor indicis tendon is located lateral to this area Q7 7.

Musculocutaneous nerve C. Axillary nerve D. Upper subscapular nerve E. Thoracodorsal nerve Q8 8. Each of the following statements concerning the cubital fossa is CORRECT EXCEPT: a.

The median nerve lies lateral to the brachial artery e. The floor is formed by the supinator and brachialis muscles Q9 9. All of the following statements concerning the brachial plexus are TRUE EXCEPT: A. The lateral cord of the brachial plexus contains fibers of ventral rami C5, C6 and C7. B. Fibers of ventral rami C8 and T1 are carried in the lower trunk, medial cord and posterior cord of the brachial plexus. C. The suprascapular nerve is a branch of the middle trunk of the brachial plexus. D. A penetrating injury one inch superior to the middle third of the clavicle could damage the trunks of the brachial plexus. E. The medial cord carries fibers which innervate muscles which adduct the digits. Q10 10. The lumbar curvature of the vertebral column becomes obvious: A. In early fetal life B. Just before birth C.
