  1. 7. Lightweight, porous bone tissue found in the epiphyses.
  2. 9. Bones with complex shapes, such as vertebrae.
  3. 11. Bones that are roughly equal in length and width, such as carpals.
  4. 12. Small openings in bone allowing blood vessels to pass through.
  5. 16. A protein that regulates bone mineralization.
  6. 20. Collagen fibers that anchor the periosteum to the bone.
  7. 21. A thin membrane lining the inner surfaces of bone cavities.
  8. 22. The spongy bone layer between compact bone in flat bones.
  9. 23. The process of blood cell formation occurring in red bone marrow.
  10. 25. Calcium and phosphate mineral deposits that harden bone.
  11. 27. Mature bone cells that maintain bone tissue.
  12. 28. The organic component of bone matrix, primarily collagen.
Down
  1. 1. The mineral component of bone, providing hardness.
  2. 2. Hyaline cartilage covering joint surfaces to reduce friction.
  3. 3. Fatty marrow found in the medullary cavity of adult bones.
  4. 4. Bone-resorbing cells that break down bone matrix.
  5. 5. Dense bone that provides strength and resistance to stress.
  6. 6. The shaft or central part of a long bone.
  7. 8. Bones that are longer than they are wide, such as the femur.
  8. 10. Small, round bones embedded in tendons, such as the patella.
  9. 13. The specialized connective tissue that makes up bone.
  10. 14. The hollow space within the diaphysis, containing bone marrow.
  11. 15. The dense connective tissue covering the outer surface of bones.
  12. 17. The protein-based component of bone, providing flexibility.
  13. 18. The rounded end of a long bone, containing spongy bone.
  14. 19. Tissue that produces blood cells, found in spongy bone.
  15. 24. Stem cells that differentiate into osteoblasts.
  16. 26. Bones that are thin and broad, such as the sternum.
