Kinesiology-ch 12 Wrist

  1. what does the radiocarpal joint include?
    • radius
    • radioulnar disk
    • scaphoid
    • lunate
    • triquetrum
  2. motion plane of the midcarpal joints?
    gliding motion
  3. Triangular fibrocartilage complex location
    disk extends from the ulnar side of radius to the ulnar styloid process
  4. purpose of Triangular fibrocartilage complex
    • cushions joint
    • stabilizeds radiocarpal joints
    • with it, the ulna bears 40% of the load
  5. wrist flexion has an arthokinematic motion in which direction?
    posterior
  6. wrist extension has an arthokinematic motion in which direction?
    anterior
  7. proximal row of carpals include:
    • scaphoid
    • lunate
    • triquetrum
    • pisiform
  8. distal row of carpals include:
    • trapezium
    • trapezoid
    • capitate
    • hamate
  9. Radial Collateral Ligament is located where?
    • styloid process to
    • scaphoid& trapezium
  10. Ulnar collateral ligament is located where?
    • styloid process to
    • pisiform and triquetrum
  11. Palmar radiocarpal ligament is located where?
    • anterior surface of wrist:
    • radius & ulna to scaphoid, lunate, and triquetrum
  12. purpose of Palmar radiocarpal ligament
    prevent extension
  13. Dorsal radiocarpal ligament is located where?
    • posterior surface of wrist:
    • radius to scaphoid, lunate, triquetrum
  14. purpose of Dorsal radiocarpal ligament
    limit flexion
  15. describe palmar fascia
    triangular-shaped fascia on palmar surface

    O.I.A.N.
    • O: medial epicondyle
    • I: palmar fascia
    • A: assists in wrist flexion
    • N: median
  19. Extensor carpi radialis longus
    OIAN
    • O: lateral epicondyle
    • I:base of 2nd metacarpal
    • A: extension and radial deviation
    • N: Radial
