The Following Are Major Steps in the Process of Intramembranous

The following are major steps in the process of intramembranous ossification:
1) Clusters of osteoblasts form osteoid that becomes mineralized.
2) Osteoblasts differentiate within mesenchymal connective tissue.
3) Spicules of bone radiate out from the ossification centers.
4) Mesenchymal cells aggregate.
