Which zone is associated with mineral deposition in the model described?

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

Answer: (D)

Mineral deposition occurs when the cartilage matrix becomes calcified in the zone where chondrocytes have enlarged and die, and the surrounding matrix gets impregnated with calcium salts. This Calcification Zone is the stage that provides the mineralized scaffold for invading blood vessels and osteoblasts to replace it with bone. While the Ossification Zone is where bone tissue is ultimately laid down, the explicit mineral deposition happens here as the cartilage matrix calcifies before ossification proceeds.
