The epiphyseal plate, also called the epiphyseal plate or epiphyseal cartilage, is a fibrous structure located between the epiphysis and metaphysis of the bone. It plays an important role in bone growth and development.
The epiphyseal plate consists of two main components: a fibrillar protein called fibrolamin and collagen fibers. Fibrolamin forms the basis of the plate and ensures its strength, and collagen fibers give it elasticity and flexibility.
The main function of the epiphyseal plate is to provide a connection between the epiphysis (the growth zone of the bone) and the metaphysis (the rest of the bone). As bone grows, the epiphysis increases in size, but the metaphysis remains unchanged. As a result, the epiphyseal plate stretches and contracts, allowing it to be flexible and adapt to changes in bone size.
In addition, the epiphyseal plate is also involved in the formation of cartilage tissue that covers the ends of growing bones. As bone grows, cartilage tissue is destroyed and replaced by bone, but the epiphyseal plate remains in place, providing a connection between bone and cartilage.
Thus, the epiphyseal plate plays an important role in bone growth and development by providing flexibility and adaptation to changes in bone size and shape. Its proper functioning is important for normal bone growth and development during childhood and adolescence.
