pain receptor
Nerve damage detector
A pain receptor is a sensory nerve ending that detects potentially harmful stimuli—extreme heat, pressure, or tissue damage—and triggers the sensation of pain.
Also called a nociceptor.
Pain receptors are found throughout the body, especially concentrated in skin, joints, and internal organs: The burn activated pain receptors in her fingertips.
