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