It is a layer of hyaline cartilage where ossification occurs in immature bones. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. Each of the four zones has a role in the proliferation, maturation, and calcification of bone cells that are added to the diaphysis. Consider the classifications of bone, and examples of each.
