growth plates
Skeletal lengthening zones
Growth plates are areas of developing cartilage near the ends of children's bones where lengthening occurs.
As a child matures, these plates gradually harden into solid bone—a process called closure.
Once the growth plates close, typically in the late teens, the bones can no longer grow longer.
Injuries to growth plates can affect bone development: The doctor checked whether the fracture damaged the growth plate.
