MEDICAL PHYSIOLOGY

Detailed explanation-1: -The brain, more specifically the hypothalamus, controls thermoregulation. If the hypothalamus senses internal temperatures growing too hot or too cold, it will automatically send signals to the skin, glands, muscles, and organs.

Detailed explanation-2: -Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.

Detailed explanation-3: -Thermoregulatory neurons in the preoptic hypothalamus The POA is thought to be the key integratory site for thermoregulation in the brain.

Detailed explanation-4: -Mechanisms of thermoregulation Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.

Detailed explanation-5: -Types of Thermoregulation. There are two primary responses to fluctuating ambient temperatures (TA) exhibited by animals: poikilothermy and homeothermy (Figure 1).
