Which zone involves hypertrophy of chondrocytes?

Which zone involves hypertrophy of chondrocytes?

• A. Calcification Zone
• B. Ossification Zone
• C. Proliferation Zone
• D. Hypertrophic Zone

Answer: (D)

Chondrocyte enlargement happens in a specific region of the growth plate where the cells dramatically grow in size, pushing the advancing front of cartilage ahead and preparing for the next steps of bone formation. This enlargement characterizes the hypertrophic zone, distinguishing it from other zones where cells are mainly proliferating (forming columns) or where the matrix is calcifying and the cells die, leading toward ossification. So, the zone that involves hypertrophy of chondrocytes is the hypertrophic zone.
