WebThe anatomical sites of somatosensory chest pain have been described above. The pain receptors are nociceptors. They are known to exist in muscle, joints, and skin. Each nociceptor has selective sensitivity to mechanical (muscle-fiber stretching), chemical (including lactic acid), and thermal stimuli. Web(the two-point discrimination threshold) reflects the density of touch receptors in that region of their skin; the smaller the two-point discrimination threshold, the higher the density of touch receptors.
