Imagine you are sitting in class on a Friday and the teacher’s droning on about why it is important to do you homework, but your mind keeps drifting off to the party you have tonight and what you want to wear. Then suddenly your friend next to you pokes you, snapping you back into reality. This is your brain multi-tasking. Just like you your brain works with many things at once like sending messages to your limbs to walk or to your mouth to tell it to swallow.
Your brain is the main organ of your body which is why it is a part of the central nervous system. Without the nervous system we wouldn’t be able to move, function or think, this is because the nervous system is what makes everything in your body work.
Think of the brain as the main computing system that controls what goes on with the other computers and the nerves are the network that relays messages from one body part to another. If one of the networks were to break, no messages would be able to be sent to that area of the body therefore that organ or limb is useless. Then imagine the main computing system shuts down. The body is now brain-dead as the nerves have no main system to get their messages from. This is why the central nervous system (the brain and the spinal cord) is covered by bone, to protect it from harm.
