When osmolarity increases above the threshold, the ever-alert osmoreceptors recognize this a the cue to stimulate the neurons that secrete antidiuretic hormone..
Secretion of… antidiuretic hormone is also simulated by decreases in blood pressure and volume, conditions sensed by stretch receptors in the heart and large arteries. Changes in blood pressure and volume are not nearly as sensitive a stimulator as increased osmolarity, but are nonetheless potent in severe conditions. For example, Loss of 15 or 20% of blood volume by hemorrhage results in massive secretion of antidiuretic hormone..
Another potent stimulus of antidiuretic hormone is nausea and vomiting, both of which are controlled by regions in the brain with links to the hypothalamus. (MORE)
The secretion of antidiuretic hormone is inhibited by both alcohol and caffeine. I'm trying to learn at what level (pituitary, where the actual secretion occurs) or the hypoth…alamus where ADH (vasopressin) is produced. (MORE)
Antidiuretic hormone (ADH) and Oxytocin are both hormones stored and secreted by the posterior pituitary gland..
The main functions of Oxytocin are aiding in sexual reproduct…ion. The main function of ADH is retaining fluid in the body.. (MORE)
Antidiuretic hormone (ADH) test, also called the Vasopressin test, is a test for the antidiuretic hormone, which is released from the pituitary gland and acts on the kidneys t…o increase their reabsorption of water into the blood. (MORE)
NO. it increases the permeability of the cells lining the collecting duct via the insertion of Aquaporin 2. This increases the volume of water that is reabsorbed resulting in …a concentrated urine. Urine is still produced but not a great amounts. (MORE)
