  2. The bones of the limbs and gridles
    Appendicular
  3. Function of bones:
    • 1. Support
    • 2. Protection
    • 3. Movement
    • 4. Storage- fat, minerals, (Ca and P)
    • 5. Blood cell formation - in marrow cavities of certain bones (hematopoiesis)
  4. How many bones do adult have?
    206
  5. Dense bone that looks smooth and homogenous
    Compact bone
  6. Bone composed of small needlelike pieces of bone and lots of open space
    Spongy bone
  7. Bone that is cube shaped and contain mostly spongy bone
    Long bone
  8. Bone that is thin, flattened, and usually curved
    Flat bone
  9. Bones that don't fit anywhere else
    Irregular bone
  10. Prebone is called?
    Hyaline cartilage
  11. The formation of bone
    Ossification
  12. Bone-forming cells
    Osteoblasts
  13. Gaint bone-destroying cells in bones, to break down bone and release calcium ions into the blood
    Osteoclasts
  14. _____ releases PTH into the blood and activates osteoclasts
    Parathyriod glands
  15. A break that does not penetrate the skin
    Closed (Simple) Fracture
  16. Broken bone that penetrates through the skin

  17. Fracture in which bone breraks into many fragments. Particularly common in the aged, whose bones are more brittle.

  22. Fracture in which bone break incompletely. Common in children, whose bones are more flexible than those of adults
    Greenstick
  23. Four steps of bone fracture repair:
    • 1. Hematoma (blood-filled swelling) is formed.
    • 2. Fibrocartilage callus formation
    • 3. Bony callus formation
    • 4. Bone remodeling
