Question

Quizplus · Accepted Answer

Intramembranous ossification is the process by which bones form from mesenchymal (undifferentiated embryonic) connective tissue. It occurs on the outer surface of the membrane and forms the bones of the skull, clavicles, and some facial bones. Cartilage is not involved in this process. It is one of two main processes of bone formation, the other being endochondral ossification.
