# Cartilage Softer and less rigid than bone. It forms the temporary skeleton of the developing fetus and gradually replaced by bone. - Cartilage is retained throughout life in certain sites of body as: - external ear - costal cartilage - air passages - articular surfaces of most bones. # Bone Hard living tissue consists of osteocytes, fibers and matrix with calcification of its extracellular matrix. A diagram shows a cross-section of bone, with four different type of cells, Osteocyte, Osteoblast, Osteogenic cell and Osteoclast. Arrows point from each cell to the bone cross-section. A diagram shows a human rib cage made of bone, with cartilage sections in-between the bones. A diagram shows a side view of the human ear, with the different cartilage sections labeled. A diagram shows a side view of the human knee, with the cartilage labeled.
