The collagen makes the bone soft and flexible.the mineral salt makes the bone fragile and strong.
The osseous tissue contains the osteogenic cells which are stem cells.they are differentiated into osteoblasts.osteoblasts build bones and are important in the external matrix of the bone.osteoclast forms osteocytes,which are the main bone cells.
