Which part of a long bone is the growth region located between diaphysis and epiphysis?

Explanation:
The main idea here is where bone length increases in a long bone. Growth in length happens at the growth plate, which sits between the shaft (diaphysis) and the ends (epiphyses). The region that lies between these parts is the metaphysis, and that’s where cartilage is produced and gradually replaced by bone as the bone lengthens during development. The periosteum is the outer covering involved in growth in width and nourishment, the diaphysis is the shaft, and the epiphysis are the ends, so they aren’t the primary growth zone. Therefore, the growth region located between the diaphysis and epiphysis is the metaphysis.
