Receptors which respond primarily to injurious or painful stimulation are called nociceptors. Within this general category are four subgroups: mechanonociceptors, mechano-heat nociceptors, mechano-cold nociceptors, and poly modal nociceptors. Nociceptors are found in skin, muscles, joints, and the viscera.
A thermoreceptor is a sensory receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.
