- The Hypothalamus Controls Body Temperature in Mammals
- 1. Body temperature in mammals is maintained at a constant level by a part of the brain called HYPOTHALA-MUS.
- 2. The hypothalamus receives information about both internal and external temperature from THERMORE-CEPTORS
- Information about the internal temperature comes from thermorecep-tors in the hypothalamus that detect blood temperature.
- Information about the external temperature comes from thermorecep-tors in the skin that detect skin temperature.
- 3. Thermorecep-tors send impulses along sensory neurons to hypothalamus, which sends impulses along motor neurons to effectors ( muscles and glands).
- 4. The neurons are part of the automatic nervous system, so it's all done unconsciously.
- 5. The effectors respond to restore the body temperature back to normal.
