A patient with damage to their preoptic area experiences hyperthermia; why does this hypothalamic damage cause elevated body temperature?

💡 Explanation

Damage to the preoptic area disrupts the body's temperature set-point because this area integrates thermal sensory input to regulate core temperature. Therefore, the body cannot effectively initiate cooling mechanisms like sweating or vasodilation, leading to hyperthermia, rather than vasoconstriction or changes in metabolic activity.
