 How do People move?

  Muscles work together to make the different parts of our body move. Muscles only pull, they can't push. One muscle pulls a body part one way and another pulls it the other way. Muscles work in groups so we can move in all directions.

1. Working together: Muscles work with joints to move the body around. Muscles are connected to the bones by tissues called tendons.

2. Joints: Joints are the places where one bone joins another to allow you to move. Joints have fluid in them to help make movement smooth.

3. Straightening: The triceps under the arm get shorter, which pulls the lower arm down. At the same time, the biceps above it relaxes and the arm straightens.

4. Bending: the biceps at the top of the arm gets shorter. This pulls the lower arm up. At the same time the triceps below the biceps relaxes.
