Epiphyseal plate is the site of bone growth. Figure 23-19: Linear growth of long bones takes place at the epiphyseal plates Slide 1 Epiphysis is the end of a long bone. Diaphysis is the shaft of a long bone. Bone gr owth Compact bone Dividing chondrocytes add length to bone. Epiphyseal plate is the site of bone growth. Chondrocyte Chondrocytes produce cartilage. Direction of growth Old chondrocytes disintegrate. Cartilage Osteoblasts lay down bone on top of cartilage. Diaphysis Newly calcified bone Osteoblast
