Review Questions

True/False - September 26, 2011

1. In addition to forensics, the fingerprints aid in grip.
2. The palmaris longus, but not the palmaris brevis, inserts onto the palmar fascia.
3. Ulnar dominate is the more common pattern of nerve supply to the hand.
4. The radial artery terminates into the princeps pollicis and the deep palmar arch.
5. Guyon's tunnel is superficial and lateral to the flexor retinaculum (transverse carpal ligament).
6. The deep branch of the ulnar is the smaller of the two terminal branches.
7. The superficial palmar arch elaborates common digital arteries and the deep palmar arch elaborates palmar metacarpal arteries.
8. Common digital arteries split to form the proper digital arteries.
9. The digital arteries are anterior (superficial) to the digital nerves.
10. The nail beds are innervated by the palmar digital nerves.
11. The superficial radial nerve extends to the nail beds of the radial 3.5 fingers.
12. The recurrent median nerve does something.
13. The deep branch of the ulnar nerve innervates all of the interossei.
14. The deep branch of the ulnar crosses the ulnar surface of the hook of the hamate.
15. The extensor retinaculum lies deep to the skin.
16. The extensor pollicis brevis and the abductor pollicis longus share a dorsal compartment of wrist/hand.
17. The extensor carpi longus is lateral to the extensor carpi brevis tendon.
18. The extensor pollicis longus tendon crosses the posterior surface of the scaphoid bone.
19. The carpal tunnel is an osseofibrous passage having metacarpal bones at the posterior border.
20. The flexor pollicis brevis is innervated by the recurrent branch of the median nerve and the superfiical branch of the ulnar nerve.
21. Each of the three hypothenar muscles are innervated by the deep branch of the ulnar nerve.
22. Both, the palmar and dorsal interossei pass anterior to the deep palmar metacarpal ligament.
23. Both, lumbricals and the interossei, pass anterior to the axis of the metacarpophalangeal joints.
24. Ulnar nerve injury "claws" each of the medial four fingers with the radial two fingers more severely clawed.
25. The lateral branch of the lateral band extends distal to the central slip.
26. The central slip attaches to the base of the proximal phalanx.
27. Intervening between the triquetrum and the distal ulnar is a fibrocartilagenous disc.
28. Collectively, the interosseous ligaments proximate the carpal bones.
29. The triangular fibrocartilaginous complex (TFCC) limits adduction of the wrist.
