Skeletal system

3. / needed to make calcium phosphate and calcium carbonate, which form the Hydroxyapatite crystal that gives bone its hardness
6. / and disease that disrupts the replacement of old bone tissue with new bone tissue
7. / osteocytes are within chambers called
8. / supports bone materialization; May have synergistic effects with vitamin D
10. / growth ___ increases length of long bones, enhances materialization, and improves bone density
13. / complex shape
14. / immature bond cells
18. / important for fat
19. / thin and curved
20. / cube-like shape equal in shape width, thickness
21. / a way bone adapt by building more bone and becoming denser improves balance and coordination
24. / a condition in which bones become weak and brittle
25. / a hallow cylindrical space within the diaphysis, contains yellow bone marrow with blood vessels reduce the weight maximizes strength
27. / needed for calcium absorption
28. / distal and proximal ends of the long bone
29. / mature bond cells

1. / thin layer of hyaline cartilage- absorbs shock at the joint
2. / stimulates absorption of calcium and phosphate from digestive track
4. / between the diaphysis and the epiphyses
5. / the The structure that connects osteocytes
7. / osteocytes form rings called
9. / bone cells that liquefy bone matrix and release calcium to the blood are called
11. / inhibits osteoclast activity in stimulates calcium uptake by bones
12. / bone lost due to menopause
15. / thin membrane that lines the medullary cavity, contains bone forming cells
16. / produces blood cells
17. / thin connective tissue shealth associated with the blood vessels
22. / small and round, embedded in tendons
23. / longer than it is wide, cylinder-like shape
26. / main shaft or body of bone long, cylindrical shape
