Question

Injury to adrenal cortex is not likely to affect the secretion of which one of the following?

• A. Aldosterone
• B. Both aldosterone and dehydroepiandrosterone
• C. Adrenaline
• D. Cortisol

Answer 1

The correct option is C Adrenaline

Adrenal glands or (suprarenal glands) are two triangular endocrine glands, each of which covers the superior surface of a kidney. Each glands has two parts, the medulla and cortex. The medulla forms the grey core of the gland; it consists mainly of chromaffin tissue and is stimulated by the sympathetic nervous system to produce adrenaline and noradrenaline. The cortex is a yellowish tissue surrounding the medulla. It is stimulated by pituitary hormones (principally ACTH) to produce three kinds of corticosteroid hormones, which affect carbohydrate metabolism (e.g. cortisol), electrolyte metabolism (e.g. aldosterone), and the sex glands (oestrogens and androgens). Thus injury to adrenal cortex is not likely to affect the secretion of adrenaline.
