Definition
| Cartilage model produced by condroblasts. chondrocytes near the center expand and calcify |
|
|
Term
|
Definition
| articular cartilage stays to cushion bone to bone contact, epiphyseal cartilage (plate) separates epiphysis from diaphysis |
|
|
Term
Endochondral Step 6
After centers of the epiphyses form secondary ossification centers |
|
Definition
| Cartilage model becomes almost completely ossified; remainder is epiphyseal plate |
|
|
Term
Endochondral Step 5
After remodeling begins |
|
Definition
| centers of the epiphyses form secondary ossification centers |
|
|
Term
Endochondral Step 4
After spongey bone |
|
Definition
| (bone collar formation, cartilage calcification, cancellous bone production)continue, remodeling begins, osteoclasts remove bone to form medullary cavity for red bone marrow. |

Term
Endochondral Step 3
perichondrium becomes periosteum |
|
Definition
| blood supply to periosteum increases, cartilage matrix becomes spongy bone, primary ossification center develops |
|
|
Term
Endochondral Step 2
After chondrocytes near the center expand and calcify |
|
Definition
| blood vessels grow into the perichondrium, perichondrium becomes periosteum |
|
|
Term
|
Definition
| (NO CARTILAGE IN INTRAMEMBRANOUS)mesenchymal cells cluster together and secrete matrix. then, an ossification center is formed and bone grows outward in struts called spicules. |
|
|
Term
|
Definition
| blood vessels begin to grow into the area. |
|
|
Term
|
Definition
| at first only spongy bone, osteons develop around blood vessels, periosteum develops. |
