GAP Topic 21 Review Questions 1. What are the two eminences of the hand, and how many muscles are located in each? a. Thenar - 3 b. Hypothenar - 3 2. What are the 5 compartments of the hand, list the muscles in each: a. Thenar b. Hypothenar c. Adductor d. Central e. Interosseous 3. The thenar compartment is primarily responsible for what actions? Abduction, Flexion and Opposition of the 1st digit (thumb) 4. Adductor pollicis is responsible for what action? Adduction 5. The hypothenar compartment is concerned with moving which digit? 5th digit 6. The central compartment contains the lumbricals, what is the action of these muscles and what digits do they act upon? Flexion of digits 2-5 at the MCPs 7. The interosseous compartment contains the dorsal and palmer interosseous muscles, what are the actions of these muscles and what digits do they act upon? Dorsal Interossei – abduction of 2nd-4th digits from the axial line also helps the lumbricals flex the MCP joints and extend the IP joints Palmar Interossei – adducts digits 2, 4 and 5 towards the axial line and also assists lumbricals in flexing the MPC joints and extending the IP joints 8. Where would you palpate the radial pulse? On the anterior distal radius just proximal to the radialcarpal joint 9. Where would you palpate the ulnar pulse? On the anterior distal ulna just proximal to the radialcarpal joint 10. Define the borders of the Anatomical Snuff box: a. Anterior: tendons of abductor pollicis longus and extensor pollicis brevis b. Posterior: tendon of extensor pollicis longus c. Floor: scaphoid and trapezium 11. What are the 9 tendons that pass through the carpal tunnel? Flexor Digitorum Superficialis (4) Flexor Digitorum Profundus (4) Flexor Pollicis Longus (1) 12. What nerve passes through the carpal tunnel? Median Nerve 13. The tunnel of guyon is found between what structures? Pisiform, Hamate, Pisohamate Ligament 14. The tunnel of guyon is associated with which nerve? Ulnar Nerve
