what are sympathetic responses to pain
Activation of the sympathetic nervous system during an episode of acute pain is known as the âfight or flightâ response. The physiological responses that take place via the sympathetic nervous system and the neuro-endocrine system are numerous and intrinsically linked. noxious stimulus or pain is a stressor that can threaten homeostasis (a steady physiological state). The adaptive response to such a stress involves physiological changes that, in the initial stages, are useful and are also potentially life-saving.
