Epiphysis
End part of long bone
Epiphysis is a term used in anatomy to describe the end portion of a long bone, which primarily functions in the process of bone growth. The epiphysis is mainly composed of cancellous bone tissue, which contains red bone marrow. It also has a thin layer of compact bone tissue that covers the epiphysis to provide strength and stability to the bone.
The epiphysis is separated from the long bone’s shaft (diaphysis), by a region called the epiphyseal plate or growth plate. The epiphyseal plate contains cartilage cells that are responsible for bone growth during childhood and adolescence. As a person reaches adulthood, the epiphyseal plate solidifies into a bony structure called the epiphyseal line, ceasing any further bone growth.
The epiphysis plays a crucial role in bone health and development, as well as maintaining physical activities such as walking, running, and jumping. It also participates in joint formation and stability, as the articular surface of the epiphysis connects with other bones to build articulations that enable movement.
