Verified step by step guidance

Understand the anatomy of a long bone: A long bone consists of several key regions, including the diaphysis (shaft), epiphysis (ends of the bone), periosteum (outer covering), and medullary cavity (inner hollow space).

Learn the process of ossification: Ossification is the formation of bone tissue. Primary ossification centers are located in the diaphysis, while secondary ossification centers develop later in the epiphysis during bone growth.

Identify the role of the secondary ossification center: The secondary ossification center is responsible for the development of the epiphysis, which contributes to the growth of the bone at the ends and the formation of the articular cartilage.

Eliminate incorrect options: The medullary cavity is the hollow space within the diaphysis, the periosteum is the outer covering of the bone, and the diaphysis is the shaft of the bone. None of these are associated with secondary ossification centers.

Conclude that the secondary ossification center is located in the epiphysis, as this is the region where bone growth occurs at the ends of long bones.
