This Article Discusses About:

The growth plate which is also called as epiphyseal plate is a hyaline cartilage plate that is present at end of long bone. This plate is present in children and adolescents. After growth is complete, this plate is replaced by an epiphyseal line. The growth plate is present in the form of a cartilage in children. This cartilage forms into a bone after complete maturity of the bones. The growth plates are more vulnerable to fractures since then mature at the very end of development, thus their occurrence is more in children since their skeletal system is not matured yet.
