Causing pain. Used of a stimulus.
Caused by or responding to a painful stimulus.
One, sometimes called nociceptive pain, results from damage to tissues, as from arthritis or a burn.
On the contrary, as the science of pain has unearthed in the last forty years or so, there are physiologically specialized systems that process nociceptive stimuli from the moment they effect peripheral receptors to the central processing of these signals in the spinal cord and the brain.
Dr. Amann's colleague Alan R. Light reports that the nociceptive nerves look exactly like ergoreceptive nerves but respond to much higher concentrations of the muscle metabolites - levels so high that they are not normally associated with intense exercise, perhaps because a signal to slow down or stop comes on before levels get that high.
Pain is felt when electrical impulses from nociceptive neurons travel to the brain.
The word 'nociceptive' comes from a Latin root meaning 'to hurt'.
