Bone Tissue 7.1 - 7.2

basic functions
1. support protection movement
  1. electrolyte balance
  2. acid base balance
    1. hemopoeisis (blood formation)
bone shape classifications
1. short bone
  1. long bone
    1. flat bone
      1. irregular bone
      2. suture
        outer compact bone
        spongy bone (diploe)
        inner compact bone
    2. Epiphysis= two knobby ends
      1. diaphysis= middle
2. pics
tissues & organs
bone coverings
1. periosteum (outer covering)
  1. outer fibrous layer
    1. inner osteogenic layer
2. endosteum (inner lining)
  1. like osteogenic
compact vs. spongy
1. pics
development
1. 1) osteogenic cell (bone stem cell)
  1. 2) osteoblast (lays down osteoiod)
    1. 3) osteocyte (mature bone cell in a lacuna w/ projections in canaliculi)
2. osteoclasts= specialized cell on bone surface for remodelling
  1. formed from stem cells in bone marrow
bone matrix
1. organic (1/3)
  1. collagen + protein carb complex
2. inorganic (2/3)
  1. 85% hydroxyapatite 10% Ca CO3
3. reinforced concrete, fiberglass, & bone
4. bone experiments
  1. soaked in acid = breaking down mineral comp
    1. flexible & rubbery
  2. baked in oven= denatured proteins
    1. brittle & broken
