Question

Dwarfism results due to deficiency of the hormone

• A. Somatostatin
• B. Thyroxine
• C. Somatotropin
• D. Mineralocortocoid

Answer 1

The correct option is C Somatotropin

Dwarfism is caused by underproduction of Somatotropins, also known as growth hormone, in childhood and is characterized by perfect proportions but small stature.

Somatostatin is hypothalamic hormone that inhibits the release of growth hormone. Therefore, somatostatin deficiency leads to uncontrolled production of growth hormone causing Gigantism (in childhood) and Acromegaly (in adults).

Thyroxine deficiency causes Myxedema in adults which is characterized by lethargy, hair loss, weight gain, puffed skin, lowered body temperature and slowed pulse rate.

Mineralocorticoid deficiency causes Addison’s disease which is characterized by bronzing of skin, disturbed glucose metabolism, loss of sodium and water and finally lower blood pressure.

Therefore, the correct answer is option C.
