Growth in width of bones

What will be an ideal response?


Growing bones widen as they lengthen through appositional growth, can occur throughout life. Bones thicken in response to increased stress from muscle activity or added weight. Osteoblasts beneath periosteum secrete bone matrix on external bone. Osteoclasts remove bone on endosteal surface. Usually more building up than breaking down which leads to thicker, stronger bone that is not too heavy.
