Which statement about thermoregulatory set points is true?
A) The set point for shivering is the same as the set point for panting.
B) In a given individual, the set points for all thermoregulatory processes are the same.
C) The set points for thermoregulatory processes are the same for all members of the same species.
D) Changes in skin temperature can change the metabolic set point.
E) The temperature of the hypothalamus serves as a positive feedback signal.

Question

Quizplus · Accepted Answer

Changes in skin temperature can signal the hypothalamus to adjust the metabolic set point, which affects thermoregulation throughout the body. The set points for different thermoregulatory processes can vary depending on a variety of factors, including external temperature, time of day, and individual physiological conditions. Therefore, choice A is incorrect. Similarly, the set points for thermoregulatory processes can differ between individuals of the same species, and even within an individual over time. Therefore, choice B and C are also incorrect. Finally, while changes in skin temperature can affect the hypothalamus, the temperature of the hypothalamus itself does not serve as a positive feedback signal. Therefore, choice E is incorrect.
