    outer shell of dense white osseous tissue
  31. Diploe
    spongy layer in cranium
  32. Epiphyseal

    • seperates marrow spaces of epiphys and diaphysis
    • (growth plate)
  33. endosteum

    • lines internal marrow cavity
  34. Perforating (sharpey) fibers
    tendons that penetrate in bone matrix come as this
  35. concentriclamella
    layers of matrix arranged around central canal
  36. Perforating (Volkamann) canals
    transverse or diagnol passages that join central canals
  37. Central (haversian or osteonic) canal
    connected with concentric lamella by canaliculi
  38. Mineral deposition
    • Crystallization process
    • Calcium, phosphate and ions taken from blood plasma
  39. 6 roles skeleton plays
    (shon predicted many eclipses around birmingham)
    • support
    • protection
    • movement
    • electrolyte balance
    • acid-base balance
    • blood formation
