Wiktionary
n. An antidiuretic hormone secreted by the pituitary gland
WordNet
n. hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules [syn: antidiuretic hormone, ADH, Pitressin]
Wikipedia
Vasopressin, also known as antidiuretic hormone (ADH), is a neurohypophysial hormone found in most mammals. In most species it contains arginine and is thus also called arginine vasopressin (AVP) or argipressin. Its two primary functions are to retain water in the body and to constrict blood vessels. Vasopressin regulates the body's retention of water by acting to increase water reabsorption in the kidney's collecting ducts, the tubules which receive the very dilute urine produced by the functional unit of the kidney, the nephrons. Vasopressin is a peptide hormone that increases water permeability of the kidney's collecting duct and distal convoluted tubule by inducing translocation of aquaporin-CD water channels in the plasma membrane of collecting duct cells. It also increases peripheral vascular resistance, which in turn increases arterial blood pressure. It plays a key role in homeostasis, by the regulation of water, glucose, and salts in the blood. It is derived from a preprohormone precursor that is synthesized in the hypothalamus and stored in vesicles at the posterior pituitary. Most of it is stored in the posterior pituitary to be released into the bloodstream. However, some AVP may also be released directly into the brain, and accumulating evidence suggests it plays an important role in social behavior, sexual motivation and pair bonding, and maternal responses to stress. It has a very short half-life between 16–24 minutes.
Usage examples of "vasopressin".
The American biochemist Vincent du Vigneaud and his associates obtained two pure substances from the posterior pituitary extracts, of which one possessed the blood-pressure-raising effect and was named vasopressin and the other possessed the uterus-stimulating effect and was named oxytocin.
There was no need to search for a third hormone with the antidiuretic effect: vasopressin possessed it in full.
Du Vigneaud found oxytocin and vasopressin to be unusually small peptides, with molecular weights just above 1000.
It happens occasionally that vasopressin may fail to be produced in adequate quantities in a particular individual.
New ones kick in, chemicals that engender a sense of security, well-being, and attachment: vasopressin in men and oxytocin in women.
In men, vasopressin helps him feel protective, and loving and, down the line, paternal.
The air was a stale mix of vasopressins, pheromones, and endorphins which floated in a blue mist a couple of meters off the floors.
Sitor Ananta objects, adjusting his noseplug to admit more vasopressin to his inhalant, sharpening his verbal ability.
