WebbThe extended amygdala is rich in AT(1) receptors and ablation of these regions has been shown to reduce sodium appetite; therefore, neurons in these sites, and to a lesser extent the lamina terminalis, are likely primary targets of an inhibitory mechanism arising from the LPBN that acts to modulate sodium appetite.. WebbThe disruption in the interstitial solution is recognized by neurons called osmoreceptors. These osmoreceptors are located in the region of the anterior hypothalamus. These osmoreceptors send a signal that causes us to drink more water, in order to restore the osmotic balance between the cells and surrounding fluid.

WebbOsmoreceptors are sensory receptors in the thirst center in the hypothalamus that monitor the concentration of solutes (osmolality) of the blood. If blood osmolality increases above its ideal value, the hypothalamus transmits signals that result in a conscious awareness of thirst. The person should (and normally does) respond by drinking water.

WebbFor such reflexes to function effectively, osmoreceptors are required to detect changes in ECF osmolality. Central osmoreceptive neurons located in brainstem nuclei that largely lack a blood-brain barrier play a crucial role in osmoregulation ( Bourque, 2008 ).

WebbThe osmoreceptors are situated in the supraoptic and paraventricular nuclei of the hypothalamus, whereas the thirst center is in the organum vasculosum of the anterior hypothalamus. As little as a 2% increase in effective ECF osmolality produced by solutes such as sodium chloride, but not urea, shrinks osmoreceptor cells and thirst center cells.
