pain pathway

The pain pathway is how your body senses and responds to pain. When you experience injury or discomfort, specialized nerve fibers detect the damage and send electrical signals through nerves to your spinal cord. From there, the signals travel to your brain, which interprets them as pain. Your brain then processes this information, prompting you to react—like pulling your hand away or feeling discomfort. This system helps protect you by making you aware of injury so you can take action to avoid further harm.
