WebMechanoreceptor. A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are innervated by sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system . 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.
