The Muscular system has different types of muscles that make your body move. Without muscles you couldn’t move. Each muscle has its own unique job which is not only moving your body, it also enables you swallow food, breath and digest. Tendons a slight different job they anchor the muscle to the bone.

INCREDIBLE MUSCLES AT WORK

The main parts of the muscular system are the tendons, muscle fibers, and muscles. There are biceps, triceps, quadriceps, gluteus Maximus, pectoral, abdominal, deltoid, and many more.

Chapter 1PARTS OF YOUR BUSY MUSCLES

One of the most known muscles is the biceps, because the guys always show them off when talking about muscles. The biceps are located in the upper part of the arm. The triceps are the opposite of the biceps and when you push a chair in you are activating this muscle. When you kick a soccer ball you activate your quadricep. The gluteus Maximus is known because is the one you sit on every day. Pectoral muscles help you do push ups. Your abdominal muscle helps you lift yourself up when laying down. And the deltoid allows you to throw a baseball.

The muscular system is very complex and each muscle does a different thing with one purpose, to move. Each part of the body comes with two or more muscles that make your body move. When you flex your leg, your arm, or even smile one muscle relaxes and the other contracts.when you flex your arm you are using the bicipital muscle area or biceps when you grab the monkey bar and swing one muscle is relaxing and the other contracting.
