What are ossification Centres?

A primary ossification center is the first area of a bone to start ossifying. It usually appears during prenatal development in the central part of each developing bone. In long bones the primary centers occur in the diaphysis/shaft and in irregular bones the primary centers occur usually in the body of the bone.

Also to know is, what is the ossification center?

The site where bone begins to form in the shaft of a long bone or the body of an irregular bone; primary ossification center. The site where bone formation continues after beginning in the long shaft or body of the bone, usually in an epiphysis; secondary ossification center.

Also, what are the types of ossification? There are two distinct types of ossification, intermembranous and endochondral. Intermembranous Ossification: This is the less common form of bone formation, being limited primarily to the flat bones of the skull such as the parietal, parts of the temporal, and parts of the maxilla.

Also question is, how many ossification centers are there?

Most bones are formed from at least two centers of ossification. The first center that appears is called the primary ossification center; its ossification usually begins in utero, and in long bones it corresponds to the diaphysis.

Where does ossification occur?

As the primary center of ossification, the diaphysis of the long bone is the first to form spongy bone tissue along the cartilage, followed by the epiphyses, which form the secondary centers of ossification and are separated from the diaphysis by a layer of uncalcified cartilage called the epiphyseal plate, where all
