The dividing cartilage cells are located in the zone of proliferation within the epiphyseal plate. This zone is where chondrocytes actively divide and contribute to bone growth.

epiphyseal plate
Chondrocytes divide rapidly and form columns of stacked cells at the epiphyseal cartilage of short and long bones. During the growth towards the ends of bones, the chondrocytes that were originally dividing in closest proximity to the center of the bone (still within the epiphyseal cartilage), die and become resorbed matrix. This matrix soon becomes calcified. Because the proliferation and destruction of chondrocytes occur at the same rate, the epiphyseal plate does not change thickness. It does, however, grow away from the middle of the bone.
Chondrocytes are primarily located within the cartilage tissue of the body. They are responsible for maintaining the extracellular matrix of the cartilage and are crucial for cartilage function and health.
A bone collar is formed around the hyaline cartilage model. The hyaline cartilage is then caviated within the cartilage model. Next, the periosteal bud is invaded with internal cavities and spongy bone is formed. This is followed by the formation of the medllary cavity as ossification continues. The epihyses are ossificated and when this process is completed, the hyaline cartilage remains only in the epiphyseal plates and articular cartilages.
Osteogenic zones are primarily seen in the growth plates of long bones, also known as the epiphyseal plates. These zones of specialized cartilage allow for bone growth during development. The different zones within the growth plate are responsible for various stages of bone formation and resorption.
matrix
The epiphyseal plate is a cartilaginous joint, also known as a synchondrosis, formed by hyaline cartilage connecting the epiphysis (end) of a bone to the diaphysis (shaft). This type of joint allows for growth in bone length during childhood and adolescence.
Intra-articular loose bodies are chondral (cartilage), osseous (bone) or osteochondral (bone and cartilage) fragments located within the joint cavity.
