Verified step by step guidance

Understand the structure of a long bone: A long bone typically consists of the diaphysis (shaft), epiphyses (ends), and metaphyses (regions between the diaphysis and epiphyses).

Identify the role of the epiphyseal plate: The epiphyseal plate, also known as the growth plate, is a layer of hyaline cartilage found in the metaphysis at each end of a long bone.

Recognize the function of the epiphyseal plate: This plate is responsible for the longitudinal growth of bones during childhood and adolescence. It allows for the addition of new bone tissue, contributing to the lengthening of the bone.

Differentiate between the epiphyseal plate and other parts of the bone: The medullary cavity is involved in the storage of bone marrow, the periosteum is a membrane covering the outer surface of the bone, and the diaphysis is the central shaft of the bone. None of these are directly involved in the lengthening of the bone.

Conclude that the epiphyseal plate is the correct location for bone growth in length: As the cartilage cells divide and mature, they are replaced by bone tissue, which results in the bone increasing in length.
