About Growth Plates. All long bones have an area called the epiphysis, which is the rounded end of the bone. The long, middle part (or shaft) of the bone is the diaphysis; the area where the bone gets wider at its end is the metaphysis. In growing kids, growth plates sit between the metaphysis and the epiphysis. Growth plates are at the end of long bones, and grow in length. They're made up of cartilage, a rubbery, flexible material (the nose, for instance, is made of cartilage).
