Explain the role of the hypothalamus in regulating the response to an increase in body temperature.
Hypothalamus can be defined as the region present in the brain that lies inferior to the thalamus and works with both the autonomic nervous system and the pituitary gland.
The hypothalamus helps in regulating the response to an increase in body temperature. As the body's temperature increases, the hypothalamus causes heat loss from the body either by sweating or vasodilating the vessels. The hypothalamus compares the body temperature with the normal body temperature. It comprises temperature-sensitive neurons. When these neurons get stimulated due to a change in the body temperature, the hypothalamus produces thermoregulatory reactions. It causes sweating or dilates a blood vessel to lower the body temperature if it is above average.
