What are the zones in endochondral bone ossification?

In endochondral ossification: The bone is formed onto a temporary cartilage model. The cartilage model grows (zone of proliferation), then chondrocytes mature (zone of maturation) and hypertropy (zone of hypertrophy), and growing cartilage model starts to calcify.

Likewise, people ask, what bones go through endochondral ossification?

Endochondral ossification is the process of bone development from hyaline cartilage. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification. In long bones, chondrocytes form a template of the hyaline cartilage diaphysis.

Furthermore, what are the 5 zones of the epiphyseal plate? A mnemonic for remembering the names of the epiphyseal plate growth zones is "Real People Have Career Options," standing for: Resting zone, Proliferative zone, Hypertrophic cartilage zone, Calcified cartilage zone, Ossification zone.

Beside this, which portion of a long bone is considered the primary center of endochondral ossification?

There are two centers of ossification for endochondral ossification. In long bones, bone tissue first appears in the diaphysis (middle of shaft). Chondrocytes multiply and form trebeculae. Cartilage is progressively eroded and replaced by hardened bone, extending towards the epiphysis.

What is the sequence of endochondral ossification?

Endochondral Ossification Endochondral ossification follows five steps. (a) Mesenchymal cells differentiate into chondrocytes. (b) The cartilage model of the future bony skeleton and the perichondrium form. (c) Capillaries penetrate cartilage.
