3. Perforating and central canals are present in compact bone. Why isn't a canal system like this required in cancellous bone? 4. Chondrocytes die as a result of calcification of cartilage during endochondral ossification. However, ossification of the bone matrix does not result in osteocyte death. Explain. 5. When the epiphyseal cartilage becomes ossified, growth at the epiphyseal plate ceases. When the epiphysis stops growing, the articular cartilage does not become ossified. Explain why it is advantageous for the articular cartilage not to be ossified.
