: : Palm of Hand - True/False

: 1. Cutaneous nerves that supply the volar surface of the fingers also supply the dorsal surfaces at the nail beds.
: a. True - Agree.
: 2. The cutaneous nerve distribution to the palm of the hand is, in part, supplied by two named branches of the median nerve.
: a. False: by median and ulnar nerve - Disagree. Palmar br. median nerve and median n. Plus Ulnar.
: 3. In anatomical position the volar surface of the thumb is in the same plane as the volar surfaces of the fingers.
: a. False: thumb is slightly pronated. - Agree. 90 deg.
: 4. Lesion of the recurrent median nerve results in an uncompensated loss of opposition.
: a. True - Agree.
: 5. The pisiform bone, a sesamoid bone, rests on the anterior surface of the trapezoid bone.
: a. False: triquetrum - Agree.
: 6. The metacarpal phalangeal joints are condyloid joints and the interphalangeal joints are hinge joints.
: a. True - Agree.
: 7. The interossei pass dorsal to the deep transverse ligament and the lumbricals pass anterior.
: a. True - Agree.
: 8. The lumbricals and the interossei are flexors at the metacarpophalangeal joint and extensors at the interphalangeal joints.
: a. True - Agree.
: 9. Damage to the ulnar nerve in the cubital tunnel causes less of a claw hand deformity than does damage at Guyon's canal.
: a. True - Agree. Ulnar paradox.
: 10. Damage to the recurrent median nerve causes the resting position of the thumb to be supinated and this deformity is known as ape hand.
: a. True - Agree.
: 11. The deep palmar arch passes posterior, and the superficial palmar arch passes anterior, to the oblique head of the adductor pollicis.
: a. True - Agree.
: 12. The surface projection of the superficial palmar arch is proximal to the surface projection of the deep palmar arch.
: a. False: superficial arch is more distal in comparison to the deep arch - Agree.
: 13. The ulnar two lumbricals are unipennate and innervated by the median nerve and the radial two lumbricals are bipennate and innervated by the ulnar nerve.
: a. False: the ulnar 2 are bipennate and supplied by ulnar nerve while the radial 2 are unipennate and supplied by median - Agree.
: 14. Intertendinous slips do not attach to extensor indicis.
: a. True - Agree.
: 15. The tendons of flexor digitorum profundus are posterior to the tendons of flexor digitorum superficialis as these tendons travel in the digital tendon sheaths.
: a. True - Agree.
: 16. The tendons of flexor digitorum superficialis split proximal to attaching to the base of the distal phalanx.
: a. False: split proximal to attach at the base of the middle phalanx - Agree.
: 17. Abductor digiti minimi shares and origin with an insertion of flexor carpi ulnaris.
: a. True (pisiform) - Agree.
: 18. Communicating arteries provide anastomoses between the plantar and dorsal metacarpal arteries.
: a. True - Agree.
: 19. Terminal branches of the radial artery are the princeps pollicis artery and the deep palmar arch.
: a. True - Agree.
: 20. The natatory ligament is more closely associated with stabilizing the palmar skin and the deep transverse metacarpal ligament is more closely associated with stabilizing bone.
: a. True - Agree.
