During middle childhood, which part of the body grows especially fast?

• A. Lower
• B. Middle
• C. Total
• D. Upper

Answer: (A)

During middle childhood, growth happens at a steady pace, with a notable emphasis on the legs. The legs lengthen more rapidly than the rest of the body, so the lower body increases in size faster than the upper body or trunk. This rapid leg growth raises height and changes body proportions, while the upper body and trunk grow more slowly in comparison. As a result, the part of the body that grows especially fast is the lower body—the legs.
