Problem 3

3. recruitment of reparative cells like fibroblasts, chondrocytes
8. shafts, long tubular portion of the long bone, composing of compact bone tissue
9. mature osteoblasts; regulate the activity of osteoblasts and osteoclasts
10. the only bone cells that involves in cell division
13. makes up an inner narrow rim of the cavity of the diaphysis of long bones
14. flat bone formation; No intermediate cartilage involved
16. build new bone; synthesize and secrete collagen fibers; initiate calcification
18. secondary bone is laid down and remodelled by osteoclasts; Hyaline cartilage is mineralized
19. a non-vascular form of Connective Tissue
20. weird shapes; Vertebrae, hip bones; support weight and dissipate loads

1. makes up the main part of the diaphyses of long bones
2. thin, flattened; sternum, ribs and most bones of the skull
4. expanded end of a long bone in the epiphyses
5. perform osteolysis; releasing the stored calcium in bones into the blood stream
6. area where diaphysis meets the epiphysis, include the epiphyseal line which is the end of the long bone
7. roughly cube shaped; Bones of the wrist and the ankle
11. all bones of the limbs except for the patella (kneecap), and the bones of the wrist and ankle
12. soft callus is formed; hyaline cartilage develops
15. Long bone formation; Requires cartilage as precursor for new bone to form
17. to modify pressure, to diminish friction
