Re: Clinical Correlate - Hand

Comments:
: : Hand Clinical Correlate - Dr. Ingrahm : : Review Questions : : These questions were not submitted by the lecturer. : : True/False - September 26, 2011 : : 1. In addition to forensics, the fingerprints aid in grip. : T : : 2. The palmaris longus, but not the palmaris brevis, inserts onto the palmar fascia. : T - palmaris brevis originates there. : : 3. Ulnar dominate is the more common pattern of nerve supply to the hand. : T : : 4. The radial artery terminates into the princeps pollicis and the deep palmar arch. : T : : 5. Guyon's tunnel is superficial and lateral to the flexor retinaculum (transverse carpal ligament). : F - superficial and medial : : 6. The deep branch of the ulnar is the smaller of the two terminal branches. : T? : : 7. The superficial palmar arch elaborates common digital arteries and the deep palmar arch elaborates palmar metacarpal arteries. : T : : 8. Common digital arteries split to form the proper digital arteries. : T : : 9. The digital arteries are anterior (superficial) to the digital nerves. : F - deep : : 10. The nail beds are innervated by the palmar digital nerves. : T - if referring to proper palmar digital nerves : : 11. The superficial radial nerve extends to the nail beds of the radial 3.5 fingers. : F - median : : 12. The recurrent median nerve does something. : T - It exists, if nothing else. : : 13. The deep branch of the ulnar nerve innervates all of the interossei. : T : : 14. The deep branch of the ulnar crosses the ulnar surface of the hook of the hamate. : F - radial : : 15. The extensor retinaculum lies deep to the skin. : It has to. Nothing anatomically significant is superficial to the skin (with reference to hand structures). : : 16. The extensor pollicis brevis and the abductor pollicis longus share a dorsal compartment of wrist/hand. : T : : 17. The extensor carpi longus is lateral to the extensor carpi brevis tendon. : T : : 18. The extensor pollicis longus tendon crosses the posterior surface of the scaphoid bone. : T : : 19. The carpal tunnel is an osseofibrous passage having metacarpal bones at the posterior border. : F - carpals : : 20. The flexor pollicis brevis is innervated by the recurrent branch of the median nerve and the superficial branch of the ulnar nerve. : F - and deep branch ulnar nerve : : 21. Each of the three hypothenar muscles are innervated by the deep branch of the ulnar nerve. : T : : 22. Both, the palmar and dorsal interossei pass anterior to the deep palmar metacarpal ligament. : F - dorsal to it : : 23. Both, lumbricals and the interossei, pass anterior to the axis of the metacarpophalangeal joints. : T : : 24. Ulnar nerve injury "claws" each of the medial four fingers with the radial two fingers more severely clawed. : F - ulnar more severely clawed : : 25. The lateral branch of the lateral band extends distal to the central slip. : T? - the lateral bands extend distal to the central slip. Are there medial and lateral branches of these? : : 26. The central slip attaches to the base of the proximal phalanx. : F - middle phalanx : : 27. Intervening between the triquetrum and the distal ulnar is a fibrocartilagenous disc. : F - between distal radius and distal ulna : : 28. Collectively, the interosseous ligaments proximate the carpal bones. : F - metacarpals : : 29. The triangular fibrocartilaginous complex (TFCC) limits adduction of the wrist. : F? - it articulates the ulna and radius, but I would think the integrity of ligaments extending along the radial side of the wrist (eg - radial collateral) would be the limiters of adduction.
