Question

Choose the correct combination

	Hormone	Source	Function
A.	Vasopressin	Posterior pituitary	Increases loss of water through urine
B.	Norepinephrine	Adrenal medulla	Increases heart beat, respiration and alertness
C.	Glucagon	$\beta$- cells of islet of Langerhans	Stimulates glycogenolysis
D.	Prolactin	Posterior pituitary	Regulates growth of mammary glands and milk formation in females.

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (B)

B

A. Vasopressin is secreted from posterior pituitary and it stimulates water reabsorption in kidneys, thereby decreasing the rate of urine production.

B. Norepinephrine or noradrenaline, is secreted from adrenal medulla in response to stress conditions in the body. It increases alertness, heartbeat, strength of heart contraction and rate of respiration.

C. Glucagon is secreted from cells of islets of Langerhans in pancreas. It increases blood glucose level by stimulating breakdown of glycogen i.e. glycogenolysis and formation of glucose i.e. gluconeogenesis.

D. Prolactin is secreted from anterior pituitary. It stimulates production of milk in mammary glands in females.

Hence, option B shows the correct combination.

So, the correct answer is 'B'.
