Question

Which one of the following hormones is NOT secreted by the adrenal gland in humans?

• A. Cortisol
• B. Epinephrine
• C. Oxytocin
• D. Aldosterone

Hint:

Remember, the adrenal glands secrete hormones such as cortisol, epinephrine, and aldosterone, while oxytocin is produced by the hypothalamus and released by the pituitary.

Answer 1

The Correct Option is C

The adrenal glands, located on top of the kidneys, produce a variety of hormones that regulate critical functions such as stress response, metabolism, and fluid balance. 
Step 1: Understanding adrenal gland secretions.
Cortisol, epinephrine, and aldosterone are all hormones secreted by the adrenal glands. 
Cortisol is a glucocorticoid hormone that helps the body respond to stress. 
Epinephrine (also known as adrenaline) is produced by the adrenal medulla and helps in the fight-or-flight response.
Aldosterone is a mineralocorticoid hormone that helps regulate blood pressure by controlling the balance of sodium and potassium.
Step 2: Oxytocin. 
Oxytocin, however, is produced by the hypothalamus and released by the posterior pituitary gland, not the adrenal glands. It plays a key role in childbirth and lactation. 
Step 3: Conclusion. 
The correct answer is (C), as oxytocin is not secreted by the adrenal glands.
