Ossification
Definition of ossification: "The process of creating bone, that is transforming cartilage (or fibrous tissue) into bone". When a child is born, a portion of their body is hyaline cartilage (relatively soft). Over time, this cartilage turns into hard bone. Bone formation is started by the activity of osteoblasts, which are bone forming cells that secrete collagen and other materials to make the bone. Bone formation process: - formation of the bone in embryo and fetus -growth during infancy childhood - remodeling of bone -repair of fracture
