Q.Give symptoms of the disease caused by hyposecretion of ADH.

Oxytocin ('birth hormone'/'milk-ejecting hormone') stimulates uterine contraction during parturition and mammary-gland contraction for milk ejection. Antidiuretic hormone (ADH/vasopressin) stimulates water reabsorption in the kidney's distal convoluted tubule and collecting ducts, reducing urine volume and raising blood pressure via vasoconstriction; ADH deficiency causes diabetes insipidus (large, dilute urine output without glucose loss) and the re …
