When NaCl is injected in the internal carotid artery, it causes release of ADH by acting on?
Osmoreceptors located in the anterior hypothalamus (preoptic nucleus), which are stimulated by NaCl injection (increase osmo­lality). Osmoreceptors have stimulatory action on thirst centre and ADH secreting supraoptic nucleus.
Paramedian nucleus
Anterior pituitary
Paraoptic nucleus
Supraoptic nucleus
