Detailed explanation-1: -It acts as a communication relay between your brain and your extremities. For example, if you touch a hot stove, the pain signals travel from your finger to your brain in a split second. In just as short a time, your brain tells the muscles in your arm and hand to snatch your finger off the hot stove.
Detailed explanation-2: -Impulses from the sensory cortex are conducted over interneurons to the prefrontal cortex of the cerebrum to be “recorded” as memories that associate the sight of a hot stove with pain. These memories cause you to be more careful when you are near a hot stove.
Detailed explanation-3: -What happens when you accidentally touch a hot plate? Sensors on your finger get activated and the information is relayed via nerves to your spinal cord (nervous system), which decides to immediately jerk back the hand by sending a signal to the arm muscles.
Detailed explanation-4: -A pain message is transmitted to the brain by specialized nerve cells known as nociceptors, or pain receptors (pictured in the circle to the right). When pain receptors are stimulated by temperature, pressure or chemicals, they release neurotransmitters within the cells.
