Thermoregulation

6 Questions

1. Define the "thermoneutral zone". Briefly explain how the body regulates temperature when the ambient temperature exceeds thermoneutral zone. (03A11) (1996)
2. Explain briefly the role of the skin in maintaining a normal body temperature. (01A5)
3. Briefly describe the influence of general anaesthesia on intraoperative temperature regulation. (97B4)
4. Explain the role of the skin in maintaining a normal body temperature. (96B2)
5. Discuss temperature regulation in the human, explaining the physics of heat transfer and how physiological control mechanisms reflexly use these to maintain constant core temperature as external temperature changes and insulation is altered. Explain the concept of thermoneutral zone and how this varies with body size. (94A1)
6. Give a brief account of the physiological consequences of hypothermia. (93A3)
