Verified step by step guidance

Understand the structure and function of the epiphyseal plate, which is responsible for longitudinal bone growth. It consists of several zones, each with distinct roles in cartilage development and ossification.

Learn the names and functions of the zones within the epiphyseal plate: Zone of resting cartilage, Zone of proliferating cartilage, Zone of hypertrophic cartilage, and Zone of calcified cartilage.

Focus on the Zone of proliferating cartilage. This zone contains actively dividing cartilage cells (chondrocytes) within their lacunae. These cells undergo mitosis, contributing to the growth of the plate and pushing the resting cartilage outward.

Compare the Zone of proliferating cartilage with the other zones: The Zone of resting cartilage contains inactive chondrocytes, the Zone of hypertrophic cartilage has enlarged chondrocytes preparing for calcification, and the Zone of calcified cartilage is where cartilage is replaced by bone tissue.

Conclude that the Zone of proliferating cartilage is the correct answer because it is the region where active cell division occurs, driving the growth process within the epiphyseal plate.
