Which is wrongly matched in vasopressin? (AIIMS Nov, 2010)
|A||V1: Vascular Smooth Muscle|
|B||V2: Distal Nephron|
|C||V3: Anterior Pituitary|
|D||V4: Central Nervous System|
· There are at least three kinds of vasopressin receptors: V1 A (also called V1), V1 B (known as V 3), and V2.
· V1 receptors are involved in causing vasoconstriction V2 receptors are present in distal nephron and decrease the urine outflow.
· The Vl B receptors (also called V3 receptors) appear to be unique to the anterior pituitary, where they mediate increased ACTH secretion from the corticotropes.
