Muscular System

From the eyes to the toes, muscles are found throughout the body, enabling us to move! They help us grab, lift, push, pull, swing, twist, and generally help us get things done every day. Some muscles do their work without us thinking about it at all--and that keeps us alive. Others need us to think about movement. This informative book details the kinds of muscles, how they work, and much more in easy-to-read text. Full-color photographs and diagrams aid readers' understanding of how this vital system works. Sidebars and fact boxes add additional information and tips to keep the muscles healthy.
