Osmometric thirst

Osmometric thirst

Cardiopulmonary receptors sense a decreased blood volume, and signal to area postrema [4] and nucleus tractus solitarii [4] as well. Cellular dehydration and osmoreceptor stimulation[ edit ] Main article: Osmoreceptor Osmometric thirst occurs when the solute concentration of the interstitial fluid increases.

This increase draws water out of the cells, and they shrink in volume. The solute concentration of the interstitial fluid increases by high intake of sodium in diet or by the drop in volume of extracellular fluids such as blood plasma and cerebrospinal fluid due to loss of water through perspiration, respiration, urination and defecation.

The increase in interstitial fluid solute concentration causes water to migrate from the cells of the body, through their membranes, to the extracellular compartment, by osmosisthus causing cellular dehydration.

They can then activate the median preoptic nucleus which initiates water seeking and ingestive behavior. Specifically, the hypothalamus appears to play a key role in the regulation of thirst.

The area postrema and nucleus tractus solitarii signal to the subfornical organ and to the lateral parabrachial nucleus. Finally, the signals are received in cortex areas of the forebrain [4] where ultimately the conscious craving arises.

The subfornical organ and the organum vasculosum of the lamina terminalis contribute to regulating the overall bodily fluid balance by signalling to the hypothalamus to form vasopressinwhich is later released by the pituitary gland.osmometric thirst thirst produced by an increase in the osmotic pressure of the interstitial fluid relative to the intracellular fluid, thus producing cellular dehydration osmoreceptor.

Osmometric thirst occurs when the osmotic balance between the amount of water in the cells & the water outside the cells becomes disturbed means when the concentration of salts in the interstitial fluid is greater than that inside the cells, resulting in the movement of intracellular water outside of .
