The epiphyseal plate, also known as the growth plate, is a hyaline cartilage plate located in the metaphysis (the region between the diaphysis and epiphysis) of long bones. It is responsible for longitudinal growth of the bone by allowing new cartilage cells to form and old ones to be replaced by bone tissue. As the cartilage cells divide and mature, they push the epiphyses away from the diaphysis and add to the length of the bone. The epiphyseal plate is eventually replaced by bone tissue and becomes the epiphyseal line, signaling the end of growth.
