How does the hypothalamus regulate body temperature?
The hypothalamus integrates the functions of the nervous and endocrine systems to provide the highest level of endocrine control.
The anterior and posterior hypothalamus, which have directly opposing effects, work together to regulate body temperature, which is one of the hypothalamus's primary functions.
While stimulation of the posterior hypothalamus initiates a thermogenic response that results in an increase in body heat and its conservation, stimulation of the anterior hypothalamus initiates a thermolytic response that causes a decrease in body temperature.
Thermogenic responses include cutaneous vasoconstriction that minimizes heat loss via radiation, the mechanism of shivering that increases heat level due to vigorous muscular activity, and the characteristic feature of panting in animals, especially in dogs. Thermolytic responses are characterized by cutaneous vasodilation, which is illustrated by body reactions like elevation in heat loss by radiation, perspiration that facilitates heat loss by evaporation, and the typical feature of panting in animals, particularly in dogs.
Additionally, the hypothalamus is capable of detecting changes in the body's blood temperature and will react accordingly.

The hypothalamus regulates body temperature by receiving signals from peripheral temperature receptors, integrating information about the current body temperature, and initiating physiological responses, such as activating sweat glands or causing shivering, to maintain homeostasis.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
