Skeletal System
Across
- 4. cartilage that helps the bones move smoothly past each other
- 6. Ossification, involves the replacement of hyaline cartilage with bony tissue
- 9. concentric plates that gives the compact bone its rigidity and hardness
- 11. site of spongy bone; responsible for articulation; long bone
- 13. mature bone cell; found in or near the lacunae; they develop extensive processes that rub through the canaliculi
- 14. cartilage that covers the ends of bones where they come together to form joints
- 15. freely movable within bone limitations; ex: hip, shoulder
- 16. skeleton that is the principal supportive structure of the body; includes the skull, vertebrae, ribs, sternum, and hyoid bone.
- 18. bone type that that is generally more flat then round
- 19. Plates, also known as growth plates
- 20. Marrow, composed of red and white blood cells and is found in bones
- 21. cylindrical units that run along compact bones to help support and strengthen the bone while also repairing and remodeling bone tissue; also known as the Haversian System
Down
- 1. bones that fill in cracks; mixed with fibrous tissue and cartilage
- 2. bone cell that rebuilds, repairs, and dissolves bone
- 3. site of compact bone; long bone; provides attachments for muscles
- 5. provides housing to the cells and keeps them alive and functional; encase osteocytes
- 7. young/immature bone cell; found near the bone surface; secretes organic substances of the matrix
- 8. any hole in your bone
- 10. skeleton that makes movement for the upper and lower limbs including arms, wrists, forearms, hands, thighs, legs, and feet
- 12. fibrous sheath for bones which provides a source of bone cells
- 17. joint movement that permits movement in only one direction; ex: ankle and elbow
