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