The Latent Evidence Section develops and identifies latent fingerprints, palm prints, and sometimes even foot prints. The section deals with virtually any area of friction ridge skin impressions that may be developed.
Vasopressin, also known as arginine vasopressin (AVP), antidiuretic hormone (ADH), or argipressin, is a neurohypophysial hormone found in most mammals.Its two primary functions are to retain water in the body and to constrict blood vessels. It is likely that vasopressin acts in conjunction with corticotropin-releasing hormone to modulate the release of corticosteroids from the adrenal gland in response to stress, particularly during pregnancy and lactation in mammals.
Vasopressin is secreted from the posterior pituitary gland in response to reductions in plasma volume, in response to increases in the plasma osmolality, and in response to cholecystokinin (CCK) secreted by the small intestine :asopressin 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.
