Match the zone with its primary temperature regulation function.

• A. Anterior zone — heat dissipation via sweating; Posterior zone — heat conservation via shivering
• B. Anterior zone — heat conservation; Posterior zone — heat dissipation
• C. Anterior zone — appetite control; Posterior zone — thirst regulation
• D. Anterior zone — circadian control; Posterior zone — circadian control

Answer: (A)

Thermoregulation is controlled by hypothalamic zones, with the anterior area acting as the heat-dissipation center. When core temperature rises, this region triggers cooling mechanisms like sweating and vasodilation to shed heat. The posterior region serves as the heat-conservation and heat-production center, activating shivering and vasoconstriction to preserve or generate warmth. So pairing the anterior zone with heat dissipation via sweating and the posterior zone with heat conservation via shivering matches the physiological roles of these areas. The other options mix in functions like appetite, thirst, or circadian control, which aren’t the primary temperature-regulating roles of these zones.
