Does Intramembranous Ossification Occur in Long Bones?

Intramembranous ossification is the process of bone development from fibrous membranes. ... Long bones lengthen as chondrocytes divide and secrete hyaline cartilage. Osteoblasts replace cartilage with bone. Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones.

What type of ossification occurs in long bones?

Endochondral ossification is the formation of long bones and other bones. This requires a hyaline cartilage precursor. There are two centers of ossification for endochondral ossification. In long bones, bone tissue first appears in the diaphysis (middle of shaft).

Do long bones have ossification centers?

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.
