Verified step by step guidance

Understand the anatomy of the epiphyseal plate: The epiphyseal plate, also known as the growth plate, is a layer of hyaline cartilage found at the ends of long bones. It is responsible for bone elongation during growth.

Identify the zones of the epiphyseal plate: The plate is divided into distinct zones, including the resting zone, proliferation zone, hypertrophic zone, calcification zone, and ossification zone. Each zone plays a specific role in bone growth.

Focus on the proliferation zone: In this zone, chondrocytes (cartilage cells) undergo rapid mitosis (cell division), increasing their number. This proliferation pushes the older chondrocytes toward the hypertrophic zone, contributing to the elongation of the bone.

Understand how elongation occurs: As chondrocytes proliferate and mature, they are replaced by bone tissue through ossification. This process occurs at the diaphyseal side of the growth plate, leading to the lengthening of the bone.

Relate the correct answer to the process: The correct answer, 'Proliferation of chondrocytes in the growth plate,' directly refers to the activity in the proliferation zone, which is the primary event leading to bone elongation.
