Where is the primary center of ossification?
diaphysis
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.

What is diaphysis and epiphysis?
The central tubular region of the bone, called the diaphysis, flares outward near the end to form the metaphysis, which contains a largely cancellous, or spongy, interior. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate.
What is the difference between calcification and ossification?
The key difference between calcification and ossification is that calcification is the process in which calcium salts build up in tissues, while ossification is the process of laying down new bone material or the formation of new bone tissue. The healthy skeleton system is made up of bones, ligaments and cartilage.
What is primary and secondary ossification center?
The primary ossification center is the first place where the bone formation begins in the axle of a long bone or in the body of an irregular bone. Conversely, the secondary ossification center is the area of ossification that appears after the primary center of ossification at the epiphysis of edges of bones.
What is an example of ossify?
Ossify means to become bony. When a baby is born, some of their “bones” are actually soft cartilage, which allows for growth. As the child grows, these soft areas ossify into actual bone. The knee cap, for example, begins to ossify between ages 3 and 6.
