n.
A sensory receptor that responds to pain.

Pain receptor Neurology Any of a class of periarticular and mucocutaneous sense organs and neural receptors–eg, reflex loops for reception and response to pain; located primarily in the skin or viscera, nociceptors respond to chemical, mechanical, or other stimuli

At the peripheral level, bradykinin sensitizes nociceptor peripheral terminals by acting on the AS- and C-fibers and evokes the release and synthesis of other second messengers, including prostaglandins, nitric oxide, and neurokinins, thus reducing pain threshold.
