Question

ACTH is secreted from the

• A. Adrenal cortex
• B. Pituitary
• C. Adrenal medulla
• D. Thyroid

Answer 1

Answer: (B)

Pituitary

Adrenocorticotropic hormone (ACTH) is secreted by anterior pituitary gland and targets adrenal cortex to produce its hormones which are namely mineralocorticoids and the glucocorticoids.

Adrenal gland secretes glucocorticoids, mineralocorticoids, sex hormones (by adrenal cortex) and epinephrine and norepinephrine (by adrenal medulla).

Thyroxine and triiodothyronine are thyroid hormones which target all tissues and stimulate metabolic rate, growth and development.

Therefore, the correct answer is option B.
