Question

Choose the correct answer from the alternatives given.
Which of the following hormones is called an antidiuretic hormone?

• A. Glucagon
• B. Prolactin
• C. Vasopressin
• D. Cortisone

Answer 1

Answer: (C)

Vasopressin

(A) Glucagon acts mainly on the liver cells and stimulates glycogenolysis resulting in increased blood sugar (hyperglycemia).

(B) Prolactin regulates the growth of the mammary glands and formation of milk in them.

(C) Vasopressin or antidiuretic hormone (ADH) acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduce the loss of water through urine (diuresis).

(D) Cortisone is the main glucocorticoid.

So the correct answer is vasopressin.
