Know endochondral ossification

1. mesenchymal cells of the embryo develop into cartilage-producing cells 2. A hyaline cartilage model of the future bone is formed 3. cartilage in the mid region of the model becomes calcified 4. the periosteum (formerly perichondrium) begins to produce a thin layer of compact bone 5. sponge bone tissue develops at the primary ossification center 6. medullary cavity is formed 7. secondary ossification centers produce spongy bone tissue of the epiphyses

The epiphyseal plate separates the epiphysis and diaphysis of a growing bone. The 5 zones of cartilage found here, in order from epiphyseal edge to diaphyseal edge are

1. zone of resting 2. proliferating 3. hypertrophic 4. calcified 5. ossification
