Regulation of Body Temperature If body temperature continues to drop, control center signals muscles to contract involuntarily. too high too low Normal body temperature 37°C (98.6°F) Control center Hypothalamus detects the deviation from the set point and signals effector organs. Control center Hypothalamus detects the deviation from the set point and signals effector organs. Stimulus Body temperature rises above normal. Effectors Dermal blood vessels dilate and sweat glands secrete. Response Body heat is lost to surroundings, temperature drops toward normal. Effectors Dermal blood vessels constrict and sweat glands remain inactive. Effectors Dermal blood vessels constrict and sweat glands remain inactive. Response Body heat is conserved, temperature rises toward normal. Stimulus Body temperature drops below normal. Receptors Thermoreceptors send signals to the control center.
