Definitions:

Nociceptors

Sensory receptors that detect signals from damaged tissue and convey pain signals to the central nervous system.

Sensory Receptors

Specialized cells or cell structures that respond to external stimuli in the environment, such as light, sound, or touch, and convert them into signals that can be interpreted by the nervous system.

Hurtful Temperatures

Extreme temperatures that can cause physical harm to the body, including hypothermia from cold and burns from excessive heat.

Gate-Control Theory

A theory that suggests pain is not merely a direct result of activation of pain fiber receptors, but is also subject to modulation by interneurons in the spinal cord that can 'gate' pain signals.
