The Skeletal System
Across
- 4. To turn the moving bone about its axis
- 6. Mature bone cells
- 7. Bones that have two or more different shapes
- 11. Tiny canals, connecting lacunae
- 14. Bones of the limbs and girdles
- 15. Developed in tendons and are often mixed with fibrous tissue and cartilage
- 18. Bones that are clearly longer in one axis than in another
- 20. A joint that is a reduced ball-and-socket configuration in which significant rotation is largely excluded
- 22. Immature bone cells
Down
- 1. A joint that is essentially immovable during growth
- 2. A break common in children; bone splinters, but break is incomplete
- 3. A circular movement, permitted at ball-and-socket, condylar, and saddle joints
- 5. Cells of epiphyseal plates which initiate bone formation
- 8. Bones that lie around the body's center of gravity
- 9. Composed of red and white blood cells in a variety of developmental forms
- 10. Decreases plasma calcium by increasing its absorption by bone
- 12. Longitudinal canal, carrying blood vessels and nerves
- 13. A fracture in which the bone ends penetrate through the skin surface
- 16. A living tissue with active cells and blood supply
- 17. Fatty connective tissue that does not produce blood cells
- 19. A fracture which is a result of twisting forces
- 21. Cells that remodel, repair, and dissolve bone
