Osmoreceptors

Osmoreceptors are sensory receptor primarily found in hypothalamus ( located in vascular organ of lamina terminalis, a circumventricular organ ) of most homoeothermic organisms that detects changes in osmotic pressure. They contribute to osmoregulation controlling fluid balance in the body. They are defined functionally as neurons that have an intrinsic ability to detect changes in osmolality.
