Question

What is intramembranous ossification? what is intramembranous ossification? the formation of bone from preexisting fibrocartilage models the formation of bone from fibrous membranes the formation of bone from preexisting hyaline cartilage models the formation of bone from preexisting elastic cartilage models?

Answer 1

 Intramembranous ossification is the formation of bone from fibrous membranes. Intramembraneous ossification is the embryonic development of flat bones from an embryonic tissue called the mesesnchyme. The bones formed through the intramembranous ossification includes the flat bones of the face, most of the cranial bones, and a good deal of the clavicles. Other bones at the base of the skull and the long bones are formed via endochondral ossifiaction. 

Answer 2

Answer:

Option B, models the formation of bone from fibrous membranes

Explanation:

In the process of Intramembranous ossification, Fetal develops to form skeletal system by replacing fibrous membrane. The mesenchymal tissue is  converted into a bone directly.  This generally happens in the bones of skull. In other ossification processes, fibrous membrane is converted into cartilage and then it is replaced by bone as in the case of endochondral ossification, where bone develops by replacing hyaline cartilage.

Hence, option B is correct.
