Pain

Description: Pain, medically termed "nociception," is a response to noxious stimuli that is conveyed to the brain by sensory neurons. The discomfort signals actual or impending injury to the body. However, pain is more than a sensation, or the physical awareness of pain; it also includes perception, the subjective interpretation of the discomfort. Perception gives information on the pain's location, intensity, and something about its nature. The various conscious and unconscious responses to both sensation and perception, including the emotional response, add further definition to the overall concept of pain.
