Maintaining thermoregulation is a function of the what?

Answer 1

Thermoregulation is part of a negative feedback loop. Basically, the body reacts to a stimulus (eg lower body temperature) and then works to reverse that stimulus - hence raising the body temperature

the negative feedback loop works when say for example, the stimulus of Falling Body temperature triggers the thermoreceptors in the Hypothalamus (a gland in the brain). These thermoreceptors trigger the hypothalamus (the Modulator in the loop) to make changes in the body to raise temperatuure. some examples are physiological things such as Vasoconstriction (constriction of blood vessels to keep warm blood in the body's core), a reduction in sweating and behaviioural responses such as putting on a jumper or standing in front of a heater. Another response caused by the hypothalamus is to create 'shivering' this rapid movement of muscle cells will increase heat production by up to 40 times and the body temperature will raise to the norm (36.8 degrees C)

hope this helps! I'm doing thermoregulation in human Biology at the moment
