  1. the body's framework constructed of cartilage and bone
  2. those bones that lie around the body's center of gravity
    axial skeleton
  3. bones of the limbs or appendages
    appendicular skeleton
  4. covers the bone ends at movable joints
    articular cartilage
  5. found connecting the ribs to the sternum
    costal cartilage
  6. largely construct the larynx (voice box)
    laryngeal cartilage
  7. reinforce other passageways of the respiratory system
    tracheal and bronchial cartilage
  8. support the external nose
    nasal cartilage
  9. separate and cushion bones of the spine
    intervertebral cartilage
  10. provides a system of levers with which the skeletal muscles can work to move the body
  11. cartilage is surrounded by a covering of dense connective tissue
  12. provides sturdy support with some resilience or give
    hyaline cartilage
  13. is much more flexible that hyaline and it tolerates repeated bending better
    elastic cartilage
  14. consists of rows of chondrocytes alternating with rows of thick collagen fibers, great tensile strength and can withstand heavy compression
  15. mostly in skeletal cartilage
  16. external ear and epiglottis
  17. intervertebral discs and knee joint
  18. looks smooth and homogeneous
    compact bone
  19. is composed of small trabeculae of bone and lots of open spaces
    spongy bone
  20. longer than they are wide, generally consisting of a shaft wih heads at either end
    long bones
  21. femur, humerus, tibia, phalanges
    long bones
  22. typically cube shaped and they contain more spongy bone than compact bone
    short bones
  23. tarsals and carpals
    short bones
  24. generally thin with two waferlike layers of compact bone sandwiching a layer of spongy bone
    flat bones
  25. skull bones
    flat bones
  26. any of the bones that have an odd shape
    irregular bones
  27. vertebrea, coxal
    irregular bones
  28. special types of short bones formed in tendons
    sesamoid bones
  29. tiny bones between cranial bones
    sutural bones
  30. the shaft of a bone
  31. fibrous membrane covering, to view the bone surface
  32. many fibers of the periosteum that penetrate into the bone
    perforating (Sharpey's) fibers
  33. bone-forming cells
  34. bone-destroying cells
  35. end of the long bone, composed of thin layer of compact bone which encloses spongy bone
  36. covers the epiphyseal surface in place of the periosteum, provides a smooth surface to minimize friction at joints
    articular cartilage
  37. a thin area of hyaline cartilage that provides for longitudinal growth of the bone during youth
    epiphyseal plate
  38. once long bone is stopped growing these areas are replaced with bone and appear as thin
    epiphyseal lines
  39. a storage region for adipose tissue
    yellow marrow
  40. involves forming blood cells found in marrow cavities
    red marrow
  41. lining the shaft, also cover the trabeculae of spongy bone and lines the canals of compact bone
