Worked practice questions

ACTH stimulates the adrenal cortex to secrete:

  1. Adrenaline hormone
  2. Aldosterone only
  3. Glucocorticoids
  4. Thyroxine hormone
Show answer and solution

Correct answer: C. Glucocorticoids

Adrenocorticotrophic hormone stimulates the adrenal cortex to make glucocorticoid steroid hormones.
