Muscles: Science Videos

This series explains how your muscles work, from the major muscle groups down to the inside of a single muscle cell. You will learn about the three types of muscle, how nerves tell muscles to move, and how muscles help keep your body warm. It ends with basketball star LeBron James asking what muscles we use to shoot a basket. This is useful for anyone interested in fitness, sports, or health careers. A basic idea of what cells are will help with the more detailed videos.
