Receptors that respond to changes in temperature are called

  • A. photoreceptors
  • B. thermoreceptors
  • C. chemoreceptors
  • D. mechanoreceptors

Thermoreceptors in the skin and hypothalamus detect heat and cold and feed the thermoregulatory centre. Photoreceptors respond to light, chemoreceptors to chemicals and mechanoreceptors to pressure and touch, so each stimulus has its own receptor family.
