nociception

Nociception is the biological process by which your nervous system detects and responds to potentially harmful stimuli, such as extreme heat, pressure, or chemicals. Nerve endings called nociceptors sense these dangers and send signals through your nerves to your brain. This process helps your body recognize injury or threat, prompting protective actions like withdrawing from pain or feeling discomfort. Nociception is a vital part of the body's defense system, playing a key role in pain perception and ensuring you respond appropriately to prevent injury.
