Bone comprises the structure of the skeletal system and provides lever arms for locomotion. Bone also plays important roles in maintaining mineral homeostasis, as well as providing the environment for [[Haematopoiesis - Overview|hematopoesis]] in [[Bone Marrow|marrow]].

The '''epiphyseal growth plate (EGP)''' is a transverse disc of cartilage between the two ossification centers and allows the bone to continue to grow in length after birth. It then closes. The EGP is a region of continuous chondroblast differentiation and maturation and can be divided into five zones:
