Stylopod Growth Plate

The stylopod growth plates are located at both ends of the long bones (humerus and femur) and contain proliferating chondrocytes responsible for the longitudinal growth of the bone. As the older chondrocytes degenerate, they are ossified by existing osteoblasts to form a new bone. The plate exists in embryos and children and is replaced by the epiphyseal line when an individual stops growing.
