Physiological Adaptation Q 20

---

The adrenal cortex is responsible for producing which substances?

  

     A. Glucocorticoids and androgens

     B. Catecholamines and epinephrine

     C. Mineralocorticoids and catecholamines

     D. Norepinephrine and epinephrine

    

    

Correct Answer: A. Glucocorticoids and androgens

---

The adrenal glands have two divisions, the cortex, and medulla. The cortex produces three types of hormones: glucocorticoids, mineralocorticoids, and androgens.

---

Option B: Epinephrine, which is a catecholamines, is produced in the medulla. It causes smooth muscle relaxation in the airways or contraction of the smooth muscle in arterioles, which results in blood vessel constriction in kidneys, decreasing or inhibiting blood flow to the nephrons.

Option C: Catecholamines are produced in the medulla. They help the body respond to stress or fright and prepare the body for “fight-or-flight” reactions.

Option D: The medulla produces catecholamines — epinephrine and norepinephrine.
