The HYPOTHALAMUS controls body temperature in mammals.
The hypothalamus receives information about body temperature from;
- Temperature receptors in the skin which detect changes on skin temperature and therefore indirectly detect environmental temperature.
- Receptors in the hypothalamus itself detect changes in the bloof flowing through it. This reflects the changes in the core body temperature.
The hypothalamus acts as a thermostat. It monitors body temperature and compares the actual temperature against a preset value. (37* in humans). Any significant deviation from this is detected and appropriate responses are initiated.
