Question

Removal of a part of pituitary affected excretory system. It causes

• A. Atrophy of adrenal cortex
• B. Atrophy of adrenal medulla
• C. Atrophy of adrenal pyramid
• D. Atrophy of renal medulla

Answer 1

The correct option is A Atrophy of adrenal cortex

Atrophy of adrenal cortex is the decreased activity of adrenal cortex. Corticoid hormones like glucocorticoids and mineralocorticoids are secreted from adrenal cortex in response to ACTH (Adrenocorticotrophic hormone) secreted by anterior pituitary. Glucocorticoids (Cortisol) increase reabsorption of sodium and water from the renal tubules. Mineralocorticoids (Aldosterone) maintain the electrolyte balance in the body by reducing the loss of sodium through urine and sweat. Hence, if a part of pituitary removed affects the secretion of ACTH, it will affect excretory system as it will lead to decreased secretion of corticoids from adrenal cortex.

So, the correct answer is 'Atrophy of adrenal cortex'.
