1. The Muscular System By: Matt Mosley and Kywand Ross

2. Why Are They So Important? Muscles are one of the most important parts of the human body. Without muscles, the body will not be able to move. The muscular system works because it can move, bend and straighten. Muscles work in opposing teams in order to create a full range of movement. One set of muscles on one side moves, and the other side then pulls the muscles back into the original position, which creates a movement.

3. Strength training builds muscle endurance along with muscle strength. Preventing muscle deterioration Increasing or maintaining bone mineral density Decreasing body fat and increasing lean muscle mass. Increasing lean muscle mass can help your body burn calories more efficiently. Why Is Strengthening Your Muscles Important?

4. Major Organs In the Muscular System The Heart is an important organ dealing with the muscular system But the heart muscle is special because, it sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Before each beat, your heart fills with blood. Then its muscle contracts to squirt the blood along. When the heart contracts, it squeezes. Your heart does this all day and all night, all the time.

5. Wait There is More!!?? Another muscle is the tongue The muscles in the back of your tongue help you make certain sounds, like the letters "k" and hard "g" (like in the word "go"). Try saying these letters slowly, and you'll feel how the back of your tongue moves against the top of your mouth to create the sounds. The front part of the tongue is very flexible and can move around a lot, working with the teeth to create different types of words. This part also helps you eat by helping to move food around your mouth while you chew. Your tongue pushes the food to your back teeth so the teeth can grind it up.

10. IS THERE A CURE FOR DYSTROPHY? There are no cures for any of the muscular dystrophies and few drugs that have any effect. Treatment of muscular dystrophy is mainly directed at preventing the complications of weakness, including decreased scoliosis, heart defects, and respiratory weaknesses

11. Are The Muscular Diseases? Dermatomyositis is one of a group of muscle diseases that involve inflammation of the muscles The inflammatory cells of the immune system attack the blood vessels that supply muscles and skin

12. Can Dermatomyositis Affect Children? Juvenile dermatomyositis is rare, affecting 3,000 to 5,000 US children under the age of 18. Children experience weakness with activities that have not been a problem before, such as getting into a car or standing up from a chair.
