Nociceptors - pain receptors - found in all tissues except cns - tissue injury activates them to transmit pain information to somatosensory system Chemical mediators of pain - prostaglandins - bradykinin - substance p Moa of chemical mediators of pain - attach to nociceptor membrane and open sodium channels - move to afferent nerve fibers, carrying impulses to spinal cord (away from injury) - impulse sent to somatosensory cortex, limbic system, frontal/parietal lobes - pain is perce...
