Skeletal System
Across
- 7. Soft tissue inside the cavities within the bones
- 8. Joint that allows no movement
- 9. Breaks down bone
- 10. Strip of tough connective tissue that holds bones together at a joint
- 13. Place where one bone attaches to another
- 14. Joints permit small amount of restrictive movement
- 18. A solid network of living cells and protein fibers that are surrounded by deposits of calcium salts
- 19. Strong connective tissue that supports the body and is softer and more flexible than bone
Down
- 1. One of a network of tubes running through compact bone that contains blood vessels and nerves
- 2. Process of bone formation, during which cartilage is replaced by bone
- 3. Number of bones in the skeleton
- 4. Small sack of synovial that reduces friction between the bones
- 5. Tough layer of connective tissue surrounding a bone
- 6. Joints that permit movement in one or more directions
- 11. Less dense tissue found inside the outer layer of compact bone
- 12. Thick layer of dense bone beneath the periosteum
- 14. The body's structural support
- 15. Mature bone cells
- 16. Produces bone
- 17. Lubricating film that enables the surfaces of the joint to slide smoothly over one another
