Describe the role of osteoblasts in intramembranous ossification
What will be an ideal response?
Osteoblasts develop in the primary ossification center and secrete organic matrix, which calcifies. In a few days' time, calcification occurs and the early bone hardens. Trapped osteoblasts then become osteocytes. Osteoblasts continue to lay down new bone, forming the trabeculae of early spongy bone.
