Answer: Osteoblasts and osteoclasts are both types of bone cells.
Explanation:
Bone is a major component of the skeletal system which is made up of highly vascular living structures that are continuously being remodelled. This is brought about by the bone cells which includes the osteoblasts and osteoclasts.
--> OSTEOBLASTS: these are the bone-forming cells that secrete collagen and other constituents of bone tissue. They are present in the center of ossification of immature bone.
--> OSTEOCLASTS: Their function is resorption of bone to maintain the optimum shape. This takes place at bone surfaces.
The balance of osteoblast and osteoclasts activity maintains normal bone structure and functions.
