Feeling a Point (or two)

How do you feel? No, I don't mean are you happy or sad? Touch the back of your hand. Did you feel it? How? When you touched your hand, you pressed on nerves in your skin. These nerves reacted and sent a message to your brain, telling you that something touched your hand. Some parts of your skin have more nerves than others. We are going to examine how these nerves are arranged, and see how that can affect the message that your brain gets.
