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.
When ever there is less water available to drink or there is increased loss of water from the body. The later may be due to diarrhoea or the heavy perspiration in hot climate of the tropical areas.

posterior pituitary gland
Hypothalamus produces it, then it's stored in the posterior lobe of the pituitary gland.
AntiDiuretic Hormone (ADH) released from the posterior part of the pituitary
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 reproduction. The main function of ADH is retaining fluid in the body.
Antidiuretic hormone i think.. - depending on how much is released controls how much water is excreeted(:
Diabetes insipidus.
antidiuretic hormone (ADH)
This would be the polypeptide hormone or the antidiuretic hormone. It is important that this hormone is secreted for the best health.
ADH, or antidiuretic hormone.
Yes. It is secreted in the posterior pituitary though.
ADH causes the kidneys to hold onto more water.
antidiuretic hormone
Antidiuretic Hormone (ADH), also called vasopressin
Hypothalamus produces it, then it's stored in the posterior lobe of the pituitary gland.
Yes, an antidiuretic hormone is excreted by the kidneys. This is also called an ADH. This type of hormone has a lot to do with the process of urination.
It is called antidiuretic hormone.It controls the urine volume mainly
AntiDiuretic Hormone (ADH) released from the posterior part of the pituitary
An antidiuretic hormone is a hormone secreted by the posterior pituitary gland.
