Six-year-old Matthew broke his femur and one of his epiphyseal plates was damaged. Explain the role of the epiphyseal plate in longitudinal growth and predict the effects of a damaged epiphyseal plate on his future longitudinal growth
What will be an ideal response?
Four of the five zones of cells associated with the epiphyseal plate are actively involved in longitudinal growth. Most of the mitotic activity occurs in the zone of proliferation. Longitudinal growth continues at the epiphyseal plate as long as mitosis is happening in the zone of proliferation. If Matthew damaged this particular zone, he may experience impaired growth in that particular epiphyseal plate of his femur as he grows.
