anatomy arthrology

  1. what is arthrology
    the study of joints
  2. synarthroses
    fibrous joints
    • bones connected by a solid mass of connective tissue proper
    • cant move or very small movements
  3. synarthroses
    cartilaginous joints
    • bones connected by a solid mass of cartilage
    • limited movement or in areas where theres twisting and compression
  4. diarthrosis or synovial joint
    • bones connected by a hollow sleeve of connective tissue proper
    • free moving
    • filled with synovial fluid
  5. fibrous joint
    interosseous membrane
    bones joined by sheets of dense connective tissue
  6. fibrous joints
    syndesmosis
    bones joined by bands or thin layers of dense connective tissue
  7. fibrous joints
    sutures
    close bony junctions with minimal amounts of connective tissue
  8. 4 types of sutures
    • plane sutures
    • squamous sutures
    • serrate sutures
    • denticulate sutures
  9. cartilaginous joints
    synchondrosis
    epiphyseal growth plate in developing bones
  10. cartilaginous joints
    symphysis
    2 types
    • intervertebral discs- between spinal cord
    • symphysis pubis- between the hips
  11. articular capsule
    fibrous membrane or capsular ligament
    • external layer
    • helps hold the bones together in the joint
  12. articular capsule
    synovial membrane
    • internal layer
    • inside the fibrous membrane
    • smooth
    • secreting ans absorbing the synovial fluid that is essential for the smooth operation of the joint
  13. synovial fluid
    coat and lubricates the articular cartilage
  14. hinge joint or ginglymi joint
    • movement in one plane
    • elbow, interphalangeal of hand and foot
  15. pivot joint or trochoid joint
    • bony pivot with an osteoligamentous ring
    • rotational movement only around the long axis of the pivot bone
    • proximal and distal median atlantoaxial
  16. ellipsoid joint or condylar joint
    • movement is about 2 orthogonal axes
    • metacarpophalangeal
  17. ball and socket joint or spheroidal joint
    • movement of all planes
    • hip
  18. plane joint
    • sliding or simple translational movements
    • carpal bones
  19. saddle joint or sellar joint
    • biaxial movement, axial rotation of the moving bone
    • thumb
  20. bicondylar joint
    • primarily move in one plane but also have limited rotation about a second axis
    • knee
  21. ligaments
    attaches bone to bone
  22. bursae
    allowes joint and surrounding tissues to allow it to move without friction
  23. retinaculum
    wraps around synovial sheaths in plave so they dont move
