Quizplus · Accepted Answer

Endochondral ossification begins with the development of a primary ossification center in the middle of the diaphysis, and ossification then proceeds from the diaphysis towards each epiphysis. Secondary ossification centers then develop in the epiphyses. This process results in the formation of a hyaline cartilage model of the bone, which is gradually replaced by bone tissue.
