A diagram of a human body with the brain and spinal cord highlighted. The brain is shown in the center of the image with the spinal cord extending from the left side of the body to the right side. The spinal cord is red and extends from the neck to the back of the head.

There are three bullet points on the image that explain how the brain interprets the messages as pain including its location intensity and nature (burning aching stinging). The first bullet point explains that the brain is experiencing pain through peripheral nerves and up the spinal cords. The second bullet point shows that the pain messages move through the peripheral nerve and up a spinal cord. The third bullet point mentions that your brain sends pain-suppressing chemicals to the pain source and triggers other responses.

The image also has a label on the top right corner that reads "1. Pain source."
