Hand Muscles

  1. What are the groups of superficial intrinsic hand muscles?
    the thenar group of muscles and the hypothenar group of muscle
  2. What are the deep intrinsic hand muscles ?
    The other intrinsic groups of muscles lie deep in the hand and include the interosseous muscles, which abduct and adduct digits 2 to 5; the adductor pollicis muscle, which adducts digit 1; and the lumbricals, which assist in flexion of the metacarpophalangeal (MCP) joint and extension of the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints
  3. The extrinsic muscles of the hand
    • Reach the hand via the carpal tunnel 
    • responsible for flexing the digit and assiting wrist in flexion
  4. What are the palm arches and where do they arise
    • They are arterial arches that seperate the intrinsicn and extrinsic muscles of the forearm
    • superficial palmar arch - derived for ulnar artery 
    • Deep palmar arch  - derived for radial artery
  5. Palmar aponeurosis
    • thickening of the palmar fasia and this is the distal attachment of the palmar longus 
    • -has
  6. palmaris brevis
  7. recurrent branch of the median nerve
    deep to the palmar aponeurosis is the recurrent branch of the median nerve
  8. Branches of the ulnar atery
    • superfical branch crosses the palm to for the superficial palmar arterial arch
    • and deep
