Answer:
Intramembranous ossification begins with differentiation of mesenchymal cells.
Explanation:
Fibrous membranes are involved in the development of the bones. The process through which this occurs is termed as the intramembranous ossification.
The cells of the mesenchyma begin to split. These cells differentiate into specialized cells each performing different functions. The following bones are formed by the process of intramembranous ossification:
- mandible
- clavicle
- some bones of the skull
