The skeletal system can move because of two main parts. Joints and muscles. Muscles work in pairs. While one muscle contracts, the other relaxes. You can see this by moving your arm up and down. Hold your muscle. You can feel the top contract and the bottom relax when your joint is bent. When you your joint lies flat, the bottom contracts and the top relaxes. Now, your arm cant move up and down without joints. The joint in your arm in known as a hinge joint. It permits movement in and out. Another joint is a ball and socket joint. This is found in your shoulder. It permits movement in a circular motion. This is how a joint helps the skeletal system move. Hope it helped :)
