Question

Which epiphyseal plate zone contains dying and deteriorating chondrocytes?

Answer 1

Answer;

Calcification zone

Explanation;

The epiphyseal plate is the area of growth in a long bone. It is a layer of hyaline cartilage where ossification occurs in immature bones. On the epiphyseal side of the epiphyseal plate, cartilage is formed.

There are 4 zones of cartilage cells within epiphyseal plate. Beginning from the epiphysis side:

• Proliferation (growth) zone
• Hypertrophic Zone
• Calcification Zone
• Ossification (osteogenic) zone

Calcification zone is the zone surrounding cartilage matrix calcifies, chondrocytes die and deteriorate.

Answer 2

The correct answer is calcification zone.

A hyaline cartilage plate in the metaphysis at each terminal of a long bone is known as the epiphyseal plate or the growth plate. It is the section of a long bone where the development of new bone occurs.

The epiphyseal plate exhibits a very specific morphology in possessing a zonal arrangement. One of the zones is the zone of calcification, in this, chondrocytes goes through the process of apoptosis and cartilaginous matrix starts to calcify.
