Across
- 3. artery that delivers food and gases to bone blood vessels.
- 4. Extracellular matrix is densely packed, mineralized.
- 6. protein that increase strength, allows bone to bend without breaking.
- 10. space in diaphysis of long bones, holds marrow
- 11. Deeper periosteum layer containing cells that can develop into osteoblasts.
- 13. production of red and white blood cells
- 15. Bone disease, weakening due bone density loss.
- 16. hormone that activates osteoclasts, resorbs bone, more Ca+ in bloodstream.
- 17. States bones remodel in response to stress placed on them over time.
- 18. Growth in bone diameter increasing width
- 19. artery that connects to central canals of osteons.
Down
- 1. Added to foods and drink, increases calcium absorption in small intestine.
- 2. Increases length of bone, epiphyseal plate
- 4. Root word for a cell that maintains
- 5. removal of old bone and deposition of new bone
- 6. hormone activates osteoblasts,deposits bone
- 7. unmineralized organic material in bone, in unmature bone.
- 8. thin CT, osteoblasts, inside of bone
- 9. cancellous bone lacks these
- 12. made by combining WBC's,releases enzymes, resorbs bone
- 14. Red marrow found here in long bones of adults.
- 20. remove cells by gradual breakdown
