Temperature Regulation

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. (http://cnx.org/content/m44733/latest/Figure_33_03_04.png)
