_______ in the hypothalamus stimulate release of antidiuretic hormone (ADH), and _______ in the aorta and carotid arteries inhibit release of ADH.

Question

Quizplus · Accepted Answer

Osmoreceptors in the hypothalamus stimulate release of antidiuretic hormone (ADH) in response to changes in plasma osmolarity, whereas stretch receptors in the aorta and carotid arteries inhibit release of ADH in response to increased blood pressure/volume. Option A is incorrect because angiotensin receptors stimulate release of aldosterone, not ADH. Option B is incorrect because chemoreceptors primarily monitor changes in blood pH and oxygen/carbon dioxide levels, not blood volume or osmolarity. Option D is incorrect because there are no known renin receptors in the hypothalamus or pituitary gland, and renin primarily regulates blood pressure by initiating the renin-angiotensin-aldosterone system. Option E is incorrect because while stretch receptors do play a role in regulating ADH release, osmoreceptors are the primary sensors for changes in plasma osmolarity.

_______ in the Hypothalamus Stimulate Release of Antidiuretic Hormone (ADH)
