An ideal tool for educating pediatric patients, this chart presents colorful, anatomically correct illustrations of the muscles of the human body. It describes and shows the kinds of muscles and what is on the inside of muscles. Illustrations demonstrate how many muscles it takes to smile (17) and how many to frown (43). The chart includes fun facts ("You have over 600 muscles in your body.") and answers to questions like "Why do muscles get tired?" and "Why do you shiver when you get cold?" Bright colors and bold figures make learning enjoyable.
