4. 3 Flexibility – ability to bend, reach and stretch comfortably Muscle – muscles control movement and are attached to bones Contract – to tighten a muscle Relax – to make less tense Joint – the place where two bones meet Range of motion – how much a joint will allow its bones, ligaments, and tendons to move Static stretch – a stretch that is held for a specific amount of time Ballistic stretch – a bouncing stretch that increases the risk for muscle injuries, unless associated with a specific sport

5. What is the muscular system? The muscular system is all of the muscles in our body that help us move. 4 www.123rf.com

6. How many muscles do you have? We have about 650 muscles. They make up half of your body weight. 5

7. Flexibility is the ability to bend, reach and stretch comfortably. You lengthen your muscles when you stretch. Stretching will increase your flexibility and range of motion. (How far your joints are able to move.) 6

8. How can stretching improve your flexibility? Why is it important to be flexible? Teacher Note: Advance to the next slide for another question. 7

9. Why is the muscular system important? Help move your bones Open and close eyelids Pump blood Help you to run and play Help you to smile Muscles control movements. But muscles cannot work alone. Teacher Note: Advance to the next slide for more information. 1-2 8
