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.
Diaphyseal face, is the opposite of the Epiphyseal face and it is when the bones stops growing, cells starts to mature and degenerate.
When the epiphyseal plate is replaced by bone, then growth at that bone stops.
The cartilage cells at the epiphyseal side are continuing to grow and divide mitotically, while the ones on the diaphyseal side are aging, dying and then osteoblasts move in to form bone. See this site for more detail and nice diagrams: http://training.seer.cancer.gov/module_a… -JSO
The epiphyseal plates are also known as the growth plates. When these are thick, especially due to injury, they can eventually cause a deformity in the child's growth and development.

epiphyseal plates
The epiphyseal plate is composed of cartilage. As the child grows, the cartilage hardens into bone. The epiphyseal plate is located at the ends of the long skeletal bones.
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.
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.
If the epiphyseal plate is damaged, it can lead to uneven limb length and abnormal bone growth. This can result in deformities and impaired function in the affected limb. Early identification and treatment are important to minimize the impact on bone growth.
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.
