Cartilage plate that servs as a growth area along the bone lenghing, it allows the dialysis of the bone to increase in length until early adulthood. When growth stops the epiphyseal plate is replaced with bone, then becoming the epiphseal line.
The epiphyseal plate is a section of hyaline cartilage that seperates the epiphysis from the diaphysis in long bones. The growth and ossification of the epiphyseal plate is responsible for the bone growing longer. Articulate cartilage is similar, however, it is found on the outside layer of the epiphysis. It grows and resorbs allowing for the remodelling of the bone. The epiphyseal line is the remains of the epiphyseal plate once it has stopped growing.
to make this question a little clearer:"once the long bone has stopped growing, these areas are replaced with bone and appear as thin, barely discernible remnants- the epiphyseal lines"
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 epiphyseal line the part of the bone that replaces the epiphyseal growth plate in long bones once a person has reached their full adult height. An epiphyseal line is visible on a standard x-ray. It looks like a thin dark streak that stretches horizontally across the rounded ends of the bone.
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.
