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