The Brain Stem
Your brain stem sits at the base of the brain and connects it to the spinal cord. The brain stem controls the flow of information between the brain and the rest of the body, and also controls many of the involuntary movements that your body does every single day.

The Information Super-Highway
Like a powerful broadband Internet connection, your spinal cord can move a lot of data very quickly. Its job is to carry messages to and from the body to the brain. There are 32 different nerves that connect directly into the spinal cord and branch outward towards the rest of the body. Reflexes are processed directly in the spinal cord, allowing you to respond very quickly to danger, without wasting time thinking about what you should do.
