Across
  1. 4. the main or midsection (shaft) of a long bone
  2. 6. bones develop from layers of specialized connective tissue
  3. 9. giant cells with 50 or more nuclei; take bone apart
  4. 11. remodeling a process in which a bone that becomes old is replaced with new bone
  5. 13. a fracture break at the distal portion of the radius
  6. 18. ossification appears in the epiphysis
  7. 19. mature bone cells that regulate calcium and occupy lacunae
  8. 20. a cartilage type of tissue that makes up a skeleton of a 5 week old fetus
  9. 21. fractures occurs at the ankles and affects both the tibia and the Fibula
  10. 22. ossification appears in the diaphysis
  11. 23. the end part of a long bone, initially growing separately from the shaft.
  12. 25. concentric circular rings around the central canal
  13. 26. Concentric rings made up of groups of hollow tubes of bone matrix
  14. 27. Maintains normal activity in the epiphyseal region
  15. 29. little channels that radiate through the matrix of lacuna
  16. 30. a plate area of cartilage near the metaphysis
Down
  1. 1. cells found in bone along the periosteum and endosteum
  2. 2. mall pockets occupied by osteocytes, regularly arranged between the lamellae
  3. 3. a canal the center of the osteon; contains blood vessels and a nerve
  4. 5. ossification Clavicle, mandible, skull, and face are developed
  5. 7. cuboidal shaped cells that form bone
  6. 8. The part of the long bone that grows during development.
  7. 10. released by the Thyroid Gland
  8. 12. a fracture within the epiphyseal region
  9. 14. bones develop as hyaline cartilage that is later replaced by bone tissue
  10. 15. forms around cartilage
  11. 16. unmineralized bone matrix
  12. 17. hormone maintains normal activity of the epiphyseal cartilage
  13. 24. a growth this forms circumferential lamellae to the outer surface of long bones
  14. 28. Ossification- Limbs, vertebrae, and hips are developed
