Across
  1. 4. huge cells made up of so many monocytes(wbc)
  2. 7. Thyroid gland-promotes osteoblasts activity and the synthesis of bone matrix
  3. 8. stem cells-unspecialized
  4. 11. too much calcium in the blood
  5. 12. pituitary gland-controls bone growth and increases calcium retention
  6. 14. abnormally low levels of calcium
  7. 16. mature bone cells-main cells
  8. 17. kidneys-stimulates the absorption of calcium de phosphate form the digestive track
  9. 18. bone shaft or body
  10. 19. line the medullary cavity
Down
  1. 1. thin layer of hyaline cartilage covering epiphyses
  2. 2. parathyroid gland-stimulates osteoclasts proliferation and activity
  3. 3. girls-ovaries boys-testes responsable for growth spurt that occurs during adolescence
  4. 5. composed of outer fibrous layer
  5. 6. bone building cells-extracelluar matrix
  6. 9. hollow cylindrical space within diaphysis
  7. 10. thyroid gland-inhibits osteoclasts activity and stimulates calcium uptake by the bones
  8. 13. proximal and distal end of the bone
  9. 15. growing bone,contains growth plate
