Across
- 1. perpendicular to the central canal and carries blood vessels and nerves.
- 3. break that does not penetrate the skin.
- 5. tiny canals that radiate from the central canal to lacunae.
- 6. remnant of the epiphyseal plate and is seen in adult bones
- 8. space inside the shaft.
- 11. prompts calcium storage to bones by osteoblasts.
- 13. grow out from the bone surface.
- 17. secure periosteum to underlying bone.
- 18. do not fit into other bone classification categories.
- 19. makes up most of bone’s length and composed of compact bone.
- 20. unit of bone containing central canal and matrix rings.
- 21. outside covering of the diaphysis and a fibrous connective tissue membrane
- 23. typically longer than they are wide.
- 26. covers the external surface of the epiphyses.
- 28. cavities in bone matrix that house osteocytes.
- 29. lines the inner surface of the shaft.
- 30. concentric circles of lacunae situated around the central canal.
- 31. process of bone formation and occurs on hyaline cartilage models or fibrous membranes.
- 32. small needlelike pieces of bone and many open spaces.
Down
- 2. growth bones grow in width.
- 4. break in a bone.
- 7. flat plate of hyaline cartilage seen in young, growing bone and causes lengthwise growth of a long bone.
- 9. thin, flattened, and usually curved.
- 10. remove bone from the inner surface of the diaphysis.
- 12. composed mostly of spongy bone enclosed by thin layer of compact bone.
- 14. indentations.
- 15. cover hyaline cartilage model with bone matrix.
- 16. activates osteoclasts (bone-destroying cells).
- 22. generally cube-shaped.
- 24. broken bone that penetrates through the skin.
- 25. opening in the center of an osteon carries blood vessels and nerves.
