Hyperosmotic Thirst: An Osmoreceptor Mechanism, a Sodium Receptor Mechanism or Both
Part of the
NATO ASI Series
book series (NSSA, volume 105)
Thirst has been divided into two categories, the first, primary, that which is involved in the regulation of body fluid homeostasis and the second that which is not involved in direct regulation of body fluids. Primary thirst has been further divided into having an extracellular origin and an intracellular origin. Extracellular thirst is involved during decreases in blood volume, resulting for example from haemorrhage, and appears to be mediated in part by angiotensin II (AII). Intracellular thirst is initiated by an increase in the ‘effective’ osmotic pressure of the blood i.e. when there is an increase in the concentration of solutes that do not readily penetrate cell membranes.
