Skeletal system
Across
- 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
Down
- 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
