Sensory receptors that detect changes in temperature and send signals to the brain for thermoregulation.

• A. Mechanoreceptors
• B. Photoreceptors
• C. Nociceptors
• D. Thermoreceptors

Answer: (D)

Temperature changes are detected by thermoreceptors, specialized sensory receptors that sense heat and cold and send signals to the brain to help regulate body temperature. These receptors relay information to the hypothalamus, the brain’s thermostat, which then triggers responses like sweating to cool down or shivering and vasoconstriction to conserve heat. Mechanoreceptors respond to mechanical forces such as touch and pressure, photoreceptors detect light, and nociceptors respond to potentially damaging stimuli (pain). While nociceptors can detect extreme temperatures that cause pain, their primary role isn’t thermoregulation. Thermoreceptors are the ones specifically dedicated to detecting temperature changes and guiding the body’s temperature control.
