What helps bones move?
If you couldn't move your bones you wouldn't be able to walk, play any sport, or do anything. That is why you have joints. Joints connect bones to bones so that they can move. Some of your most popular joints like the hinge, ball-n-socket, sliding, saddle, and the pivot joints are very important in your skeletal system. Your hinge joint makes you able to move in only way, just like a hinge. Your hinge bone is in your knuckle, elbow, toe, and your knee. Your ball-n-socket joint lets you move freely in every position. If you ever throw or kick a ball you have to use your shoulder joint and your hip bone, which are your two ball-n-socket joints you have in your body. Next are your sliding. Some of these bones are in your neck, where your fingers meet your hand, also where your toes meet your feet, ankle, and last is your wrist (this is one of your most common kind of joints. They let you you move forward, backward, right, and left. Almost like a ball-n-socket except in ball-n- socket your bone rotates. These are the most common kinds of joints.
