Which of the Following is Formed by Intramembranous Ossification

Question

Which of the following is formed by intramembranous ossification?
A) roof of the skull
B) carpal bones
C) femur
D) clavicle
E) the roof of the skull and the clavicle

Accepted Answer

The roof of the skull and the clavicle are both formed by intramembranous ossification, which is the process of bone formation directly from mesenchymal cells within a membranous layer. The carpal bones are formed by endochondral ossification, which involves the transformation of cartilage into bone, while the femur is also formed by endochondral ossification but from a different type of cartilage template.
