Document Summary
Affects every age, sex, race, and socioeconomic class. An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Normal functioning of physiologic systems that leads to the perception of noxious stimuli as being painful. The processes by which noxious stimuli activate nociceptors. Noxious stimuli cause the release of a number of excitatory compounds which move pain along the pain pathway. The result of the neural activity associated with transmission of noxious stimuli. Requires activation of higher brain structures for the occurrence of awareness, emotions, and drives associated with pain. Occurs at every level from the periphery to the cortex and involves many different neurochemicals. Results from abnormal processing of sensory input by the nervous system as a result of damage to the peripheral or central nervous system. Sustained by mechanisms that are driven by damage to or dysfunction of the peripheral or central nervous system.
