In humans, body temperature is controlled by the thermoregulatory centre in the hypothalamus.
It receives input from two sets of thermoreceptors: receptors in the hypothalamus itself monitor
the temperature of the blood as it passes through the brain (the core temperature), and receptors
in the skin (especially on the trunk) monitor the external temperature. Both sets of information
are needed so that the body can make appropriate adjustments. The thermoregulatory centre sends
impulses to several different effectors to adjust body temperature:
