Across
  1. 4. cartilage that helps the bones move smoothly past each other
  2. 6. Ossification, involves the replacement of hyaline cartilage with bony tissue
  3. 9. concentric plates that gives the compact bone its rigidity and hardness
  4. 11. site of spongy bone; responsible for articulation; long bone
  5. 13. mature bone cell; found in or near the lacunae; they develop extensive processes that rub through the canaliculi
  6. 14. cartilage that covers the ends of bones where they come together to form joints
  7. 15. freely movable within bone limitations; ex: hip, shoulder
  8. 16. skeleton that is the principal supportive structure of the body; includes the skull, vertebrae, ribs, sternum, and hyoid bone.
  9. 18. bone type that that is generally more flat then round
  10. 19. Plates, also known as growth plates
  11. 20. Marrow, composed of red and white blood cells and is found in bones
  12. 21. cylindrical units that run along compact bones to help support and strengthen the bone while also repairing and remodeling bone tissue; also known as the Haversian System
Down
  1. 1. bones that fill in cracks; mixed with fibrous tissue and cartilage
  2. 2. bone cell that rebuilds, repairs, and dissolves bone
  3. 3. site of compact bone; long bone; provides attachments for muscles
  4. 5. provides housing to the cells and keeps them alive and functional; encase osteocytes
  5. 7. young/immature bone cell; found near the bone surface; secretes organic substances of the matrix
  6. 8. any hole in your bone
  7. 10. skeleton that makes movement for the upper and lower limbs including arms, wrists, forearms, hands, thighs, legs, and feet
  8. 12. fibrous sheath for bones which provides a source of bone cells
  9. 17. joint movement that permits movement in only one direction; ex: ankle and elbow
