The locomotor system is made up of muscles, bones, joints and tendons. We use it to move, eat and speak.
We have around 600 muscles. They are elastic and flexible.
We can move them, or they move automatically (like heart).
We have around 200 bones. They are hard, rigid and light. They support our body. And protect some organs, like heart, lungs and brain.
Joints join two or more bones. They allow us to move.
Tendons join a muscle to a bone.
