The presence of an epiphyseal plate indicates that:

the bone is undergoing repair after a fracture

the bone is composed entirely of compact bone

bone growth in length is still occurring

the bone has reached its full adult size

Verified step by step guidance

Understand the function of the epiphyseal plate: The epiphyseal plate, also known as the growth plate, is a layer of hyaline cartilage found in the metaphysis of long bones. It is responsible for longitudinal bone growth during development.

Recognize the process of bone growth: Bone growth in length occurs through endochondral ossification, where cartilage is replaced by bone tissue. This process continues until the epiphyseal plate is replaced by the epiphyseal line, signaling the end of growth.

Eliminate incorrect options: The presence of an epiphyseal plate does not indicate bone repair after a fracture, nor does it mean the bone is composed entirely of compact bone. These are unrelated to the function of the growth plate.

Focus on the correct option: The presence of an epiphyseal plate indicates that bone growth in length is still occurring, as the cartilage is actively being replaced by bone tissue during development.

Conclude the reasoning: Once the epiphyseal plate is fully ossified and becomes the epiphyseal line, the bone has reached its full adult size, and longitudinal growth ceases.
