Question

Quizplus · Accepted Answer

The preoptic area of the hypothalamus is responsible for regulating body temperature and can detect changes in external environmental temperature. When the body detects that it is too warm, the preoptic area activates cooling mechanisms, such as sweating and dilation of blood vessels near the skin, to help lower body temperature. Conversely, when the body detects that it is too cold, the preoptic area activates warming mechanisms, such as shivering and constriction of blood vessels near the skin, to help raise body temperature. Therefore, Robert's sensations of being too hot or too cold are likely due to the actions of his preoptic area, which is responsible for regulating body temperature.
