Question

Quizplus · Accepted Answer

Long bones increase in length due to the activity of the epiphyseal plate, which is made up of cartilage cells. As these cells divide and mature, they push the epiphysis (end of the bone) away from the diaphysis (shaft). Eventually, the epiphyseal cartilage becomes ossified (turns into bone), and this marks the end of longitudinal bone growth.
