The epiphyseal plate is a cartilaginous structure at the end of long bones that is involved in bone growth during childhood and adolescence. Once growth stops, this cartilage is replaced by bone, forming the epiphyseal line. The epiphyseal plate allows bone growth, while the epiphyseal line indicates that growth has ceased.
Bone marrow, articular cartilage, epiphyseal line, and epiphyseal plate are all components of the skeletal system. Articular cartilage covers the ends of long bones that form joints. The epiphyseal line represents a remnant of the epiphyseal plate, which is a cartilaginous plate in long bones where growth occurs. Bone marrow is the soft tissue found inside bones that produces blood cells and stores fat.
The epiphyseal line is a remnant of the epiphyseal growth plate, which is a cartilaginous structure present in growing bones. Once bone growth is complete, the growth plate calcifies and transforms into the epiphyseal line, indicating the end of longitudinal bone growth.
The epiphyseal line on the humerus is also known as the line of fusion or the metaphyseal scar. This line represents the site where the growth plate has fused and bone growth has ceased.
The epiphyseal plate ossifies and becomes the epiphyseal line in long bones. This begins at puberty.
Long bones such as the femur length along the epiphyseal plate that turns into the epiphyseal line in adults when their growth is complete.
The replacement of the epiphyseal plate by the epiphyseal line indicates that the individual has reached skeletal maturity, and bone growth has stopped in length. Further bone growth can still occur in width and density through a process known as appositional growth.
The cartilage cells at the epiphyseal side are continuing to grow and divide mitotiacally and the diaphyseal side are aging and dying and the osteoblast move in to form bone. So they are growing on the ends side and in the middle side of the Epiphyseal line they are dying and form bone.
The layer you are referring to is the epiphyseal plate, also known as the growth plate. It is found at the ends of long bones in children and adolescents, allowing the bone to lengthen as the cartilage cells multiply and are replaced by new bone tissue. Once growth is complete, the epiphyseal plate ossifies and becomes the epiphyseal line.
