This story describes how the brain is able to send information to and from the body.
- The brain is made up of billions of cells called neurons. (like puzzle pieces – afferents & efferents)
- There are 2 main ways that neurons “talk” – chemically and electrically. (both are REALLY fast)
- Neurons connect different parts of the brain together and they connect the brain to different parts of the body. (nerves)
