  1. Name the functions of skeletal system
    • support
    • protection
    • movement
    • storage
    • blood cell formation
  2. stores energy found in bones
    yellow marrow
  3. fills internal cavities of bones, blood cells through hematopoesis
    red marrow
  4. blood cell formation (red, white, platelets)
    hematopoesis
  5. longer than wider mostly compact bones
    long bones
  6. cube shaped and contain mostly spongy bone
    short bones
  7. thin, flattened, usuallly curved
    flat bones
  8. two thin layers of compact bone sandwiching by a layer of spongy bone between them
    flat bones
  9. called wormian bones-found between flat bones in the skull
    sutures
  10. small, flat and develop inside tendons
    sesamoid bones
  11. commonly located near joints of the knees, hands, and feet.
    sesamoid bones
  12. carpals and tarsal are what type of bones
    short bones
  13. parietal skull bones and other skull bones, ribs, sternum are examples of what type of bone
    flat bone
  14. vertebrae, bones of the pelvis, some skull bones are examples of
    irregular bones
  15. patella is an example of
    sesamoid bone
  16. also called the shaft makes up the bone length
    diaphysis
  17. medullary cavity is lined with
    endosteum, a thin layer of squamous epithelium
  18. covers the diaphysis and the bones
    periosteum
  19. two types of cellss in periosteum
    osteoblasts and osteoclasts
  20. this type of cell raise calcium levels
    osteoclast
  21. form/grows bone through a process called osteogenesis
    osteoblasts
  22. in adults bones-thin line of bony tissue spanning the epighysis
    epiphyseal line
  23. flat plate of hyaline cartilage seen in young, growing bone (18-21)
    epiphyseal plate
  24. mature bone cells
    osteocytes
  25. bone tissue is made of calcium salts
    matrix
  26. layers of the matrix is called
    lamellae
  27. the matrix contains
    calcium, phosphate crystals
  28. tiny, narrow passageways through bone matrix which form a branching network of nutrients, wastes, and gases
    canaliculi
  29. Haversian is also called
    osteon
  30. run perpendicular to the surface and connect together central canals.
    perforating (Volkmann's) canal
  31. central canal+the lamellae (matrix rings)=
    Osteon (Haversian system)
  32. bony bars designed to take stress and for strength
    tabeculae
  33. bone formation is called
    osteogenesis
  34. blood cell formation is called
    hematopoesis
  35. a central (Haversial) canal contains
    blood vessels and nerves
  36. the space in an osteon where osteocytes are located
    lacunae
  37. the nonliving/inorganic portion of the compact bone
    matrix of calcium salts
  38. connective tissue found covering the epiphysis
    articular cartilage
  39. the pull of ____can reshape a bone
    gravity
  40. marrow cavity contains this type of storage connective tissue
    adipose tissue
  41. ends of a long bone
    epiphysis
  42. the location where blood cell formation occurs
    marrow cavity
  43. the canal where a blood vessel travels through the bone
    central or Haversial canal
  44. canls connecting central canal
    perforating canal
