What is the name of the bone formation process in the fetus where cartilage is absent?

Endochondral Ossification
Intercalated Growth
Intramembranous Ossification
Appositional Growth

The correct answer is: Intramembranous Ossification

Intramembranous ossification is the process by which bones form directly from mesenchymal cells without the presence of cartilage. This process occurs mainly in the skull and facial bones, as well as the clavicles. Option A, endochondral ossification, is the process by which most bones in the body, including long bones like the femur and humerus, are formed from hyaline cartilage. Option B, intercalated growth, is a term used to describe the growth of muscles. And option D, appositional growth, refers to the growth of bones in width rather than length.
