Skeletal system

1. / a condition in which bones become weak and brittle
5. / bone lost due to menopause
7. / main shaft or body of bone long, cylindrical shape
9. / distal and proximal ends of the long bone
10. / longer than it is wide, cylinder-like shape
13. / complex shape
15. / needed to make calcium phosphate and calcium carbonate, which form the Hydroxyapatite crystal that gives bone its hardness
17. / supports bone materialization; May have synergistic effects with vitamin D
18. / needed for calcium absorption
21. / stimulates absorption of calcium and phosphate from digestive track
23. / immature bond cells
26. / osteocytes form rings called
27. / growth ___ increases length of long bones, enhances materialization, and improves bone density
28. / thin layer of hyaline cartilage- absorbs shock at the joint
30. / small and round, embedded in tendons

2. / mature bond cells
3. / between the diaphysis and the epiphyses
4. / a hallow cylindrical space within the diaphysis, contains yellow bone marrow with blood vessels reduce the weight maximizes strength
6. / a way bone adapt by building more bone and becoming denser improves balance and coordination
8. / important for fat
11. / the The structure that connects osteocytes
12. / thin connective tissue shealth associated with the blood vessels
14. / thin membrane that lines the medullary cavity, contains bone forming cells
16. / inhibits osteoclast activity in stimulates calcium uptake by bones
19. / thin and curved
20. / bone cells that liquefy bone matrix and release calcium to the blood are called
22. / osteocytes are within chambers called
24. / cube-like shape equal in shape width, thickness
25. / and disease that disrupts the replacement of old bone tissue with new bone tissue
29. / produces blood cells
