Question

Corticoid hormones are mainly secreted by ________.

• A. Adrenal cortex
• B. Gonad
• C. Placenta
• D. All of the above

Answer 1

The correct option is D All of the above

Corticoids are a group of steroid hormones. Glucocorticoids and mineralocorticoids are the steroids released by the adrenal glands. Glucocorticoids are involved in carbohydrate, lipid, protein, and purine metabolism. Mineralocorticoids are involved in regulating plasma sodium and potassium concentrations. Testosterone secreted by the testis (male gonad) is a corticoid hormone and responsible for male sexual characteristics. Estrogen and progesterone are secreted by the ovaries (female gonad) and are responsible for female sexual characteristics. The placenta secretes human chorionic gonadotropin that maintains pregnancy.

So, the correct option is option D.
