Question

Function of somatostatin is to

• A. Stimulate pituitary synthesis and release gonadotropins
• B. Inhibit the release of gonadotropins from pituitary
• C. Stimulate pituitary and promotes secretion of growth hormone
• D. Inhibit the release of growth hormone from pituitary

Answer 1

The correct option is D Inhibit the release of growth hormone from pituitary

A. Gonadotrophin-releasing hormone (GnRH) stimulates pituitary and release follicle stimulating hormone (FSH) and luteinizing hormone (LH) which are gonadotropins.

B. Luteinizing hormone (LH) inhibit the release of gonadotropins from the pituitary.

C. Growth hormone-releasing hormone (GHRH) stimulates pituitary and promotes secretion of growth hormone.

D. Somatostatin inhibits release of growth hormone from the pituitary and also insulin and glucagon.

So, the correct answer is 'Inhibit the release of growth hormone from pituitary'.
