What Is Intramembranous Ossification?
Intramembranous ossification occurs during mammalian development within the womb and is the process by which flat bones such as some of the bones of the skull and the collarbones are created from connective tissue. It also is the process by which injured bones heal and occurs occurs when bones are broken or damaged in order to reconstruct the bone. Also occurring during embryonic development is endochondral ossification, a process in which bones are produced from cartilage. Endochondral ossification occurs in the development of long bones such as the arms and legs. In intramembranous ossification, there is no cartilage present, and the bones develop from other connective tissues instead.
