Osmoreceptors are located in

Osmoreceptors are sensory receptors present in supraoptic nucleus. Hypothalamus regulates the water balance of the body through osmoreceptors by controlling water loss. The increased plasma osmolality stimulates the osmoreceptors in supraoptic nucleus. The stimulated neurons of supraoptic nucleus send impulses to the posterior pituitary gland to secrete ADH. ADH reaches tge kidney tubules through blood and causes increased absorption of water from collecting ducts of the kidneys. Thus water loss is decreased.
