Following statements are regarding to the regulation of body temperature.
A. The temperature-regulating center is located in the anterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the skin and about core temperature from thermoreceptors in the anterior hypothalamus itself.
B. The temperature-regulating center is located in the posterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the posterior hypothalamus itself and about core temperature from thermoreceptors in the skin.
C. If core temperature is below the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.
D. If core temperature is above the set-point temperature, then heat-dissipating mechanisms are activated.
E. If core temperature is below the set-point temperature, then heat-dissipating mechanisms are activated.
F. If core temperature is above the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.
