Summary Introduction
To explain:
The role of the hypothalamus in regulating the response to an increase in body temperature.
Concept introduction:

- Thermoreceptors in the hypothalamus sense the temperature of the blood. When blood temperature begins to decrease, the hypothalamus releases TRH, which stimulates the release of TSH from the anterior pituitary gland. TSH stimulates the thyroid gland to release thyroid hormone (TH). TH stimulates an increase in body temperature, which causes the hypothalamus to decrease the release of TRH. In this reflex pathway, what is the response? A) Increased body temperature B) Increased release of TH C) Thermoreceptors D) Decreased release of TRHarrow_forwardThe _____ is an area of the hypothalamus that initiates eating and controls several aspects of feeding behavior and metabolic processes.
