Body Messages

Nerves are like tiny roads that carry messages through your body. Some nerves bring news from your skin to your spinal cord and brain, and others carry orders back to your muscles.

In the picture

  1. Skin on the calf: the spot where the cat’s touch is felt
  2. Spinal cord in the backbone: the route that carries the touch message upward
  3. Brain: the place that receives the message and decides what to do
  4. Calf muscle: the part that gets the order to move the leg

Examples

  • Touching a hot cup and pulling your hand away
  • Feeling a mosquito land on your arm and swiping it off
