Endochondral ossification involves the replacement of hyaline cartilage with bony tissue. ... At the same time, the cartilage in the center of the diaphysis begins to disintegrate. Osteoblasts penetrate the disintegrating cartilage and replace it with spongy bone. This forms a primary ossification center.
What are the steps in endochondral ossification?
- Cartilage enlarges; Chondrocytes die.
- blood vessels grow into perichondrium; cells convert to osteoblasts; shaft becomes covered with superficial bone.
- more blood supply and osteoblasts; produces spongy bone; formation spreads on shaft.
- Osteoclasts create medullary cavity; appositional growth.
What is endochondral ossification and when does it occur?
Endochondral ossification is the process by which bone tissue is formed in early fetal development. It begins when MSCs start to produce a cartilage template of long bones, such as the femur and the tibia, upon which bone morphogenesis occurs.
