Study Notes
The Science of Thirst: Understanding the Mechanisms Behind the Sensation
- Saliva levels in the mouth strongly correlate with water deficit
- Anaesthetising the mouth of thirsty dogs and humans alleviates thirst
- Directly placing water into the stomach of a thirsty animal does not alleviate thirst as effectively as drinking through the mouth
- Thirsty camels can drink 30% of their body weight in water in 10 minutes, long before physiological relief
- Lack of salivary glands does not hinder normal drinking in animals and humans
- The insula cortex plays a role in the subjective sensation of thirst
- The hypothalamus, particularly the median preoptic nucleus, is suggested as a central brain area responsible for thirst
- Specific cells in the hypothalamus are sensitive to variations in salt levels in blood plasma
- The hypothalamus controls the release of Antidiuretic Hormone (ADH) to regulate water retention
- Peripheral systems, particularly in the kidneys, work cooperatively and independently of the hypothalamus in regulating thirst
- The kidney detects changes in blood pressure and releases hormones that affect the CNS and drinking behavior
- Thirst results from a complex interplay of peripheral and central mechanisms, involving departures from set points triggering the sensation of thirst and drinking behavior
