The process of endochondrial ossification

The process of endochrondrial ossification is usually described in a rather violent fashion. If one changed the words a bit, that would be the full scale invasion of a great civilisation by another one.

1. The cartilage is invaded by blood vessels right in the middle to form the primary ossification centre. (read base of attack)

2. Chondrocytes undergo modifications to form longitudinal columns.

3. These then deteriorate. (Torture of the locals, followed by execution)

4. Osteoblasts then enter cartilage. (like tanks signifying hostile take over. Osteoblast does sound like the name a of futuristic tank from Red Alert, doesn't it?)

5. Diaphysis starts from the centre. (A diaphysis is essentially the long shaft of the bone, the expansion of the conquered territories)

6. Ossification begins from the centre, as osteoblasts move lengthwise up and down the shaft. The Cartilage continues to grow outward. (As though a desperate attempt to escape the vicious osteoblasts)

7. Epiphyseal plates around on the ends. Meanwhile, osteoblast catches up with cartilage. (and guns them down. Well, turns them into bone).

8. Epiphyseal plates ossify.

The city has fallen.
