Question

Goitre is pathologically associated with

• A. Thyroxine
• B. Testosterone
• C. Progesterone
• D. Glucagon

Answer 1

The correct option is A Thyroxine

A. Thyroxine is secreted from thyroid gland. It stimulates the consumption of oxygen by metabolically active tissues and also increases the oxidation of glucose in tissues.

B. Testosterone is the male sex hormone secreted from testis and stimulates the development of secondary sexual characteristics in males.

C. Progesterone is a steroid female sex hormone which is also known as pregnancy hormone. It maintains the inner lining of uterus which aids in implantation of embryo in the uterus.

D. Glucagon is secreted from alpha cells of islets of Langerhans of pancreas. It increases blood sugar level by stimulating glycogenolysis (i.e. break down of glucose) and gluconeogenesis (synthesis of glucose).

Goitre is a condition in which thyroid gland becomes hyperactive and enlarged to secrete large levels of thyroxine hormone when there is iodine deficiency in body.

So, the correct answer is 'Thyroxine'.
