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

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

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
