|
Definition
| Intramembranous (babies) and endochondral (cartilage to bone) |
|
|
Term
| Five Steps of Endochondral Ossification |
|
Definition
| 1. Chondrocyes at the center of the growing cartilage model enlarge and thend die as the matrix calcifies. 2. Newly derived osteoblasts cover the shaft of the cartilage in a thin layer of bone. 3. blood vessels penetrate the carilage. New osteoblasts form a primary ossification center. 4. The bone of the shaft thinkens, and the cartilage near each epiphysis is replaced by shafts of bone. 5. Blood vessels invade the epphyses and osteoblasts form secondary centers of ossification. |

| 4 Steps of Fracture Repair. |
|
Definition
| 1. Facture Hematoma 2. Internal callus forms, spongy bone unites inner deges, externall callus of cartilage and bone stabilizes the outer edges. 3. Cartilae of the external callus has been replaced by bone, and struts of spongy bone now unite the broken ends. Fragments of dead bone and the areas of bone closest to the break have been removed and replace. 4. Done, some swelling, will go away |
