Question

Identify the statement/s given below that does not correspond to the functions of cortisol i) Maintains cardiovascular system and kidney functions
ii) Produces anti-inflammatory reactions
iii) Maintains electrolyte balance, osmosis and blood pressure
iv) Suppresses immune response
v) Stimulates RBC production

• A. iii only
• B. iv only
• C. i and ii only
• D. iii and iv only

Hint:

Cortisol regulates stress and inflammation, not electrolyte balance (that’s aldosterone).

Answer 1

The Correct Option is A

• Cortisol Functions: Cortisol, a glucocorticoid, is a stress hormone with specific roles.
• Statement Analysis:
  • (i) Maintains cardiovascular system and kidney functions: True, cortisol helps regulate blood pressure and kidney function.
  • (ii) Produces anti-inflammatory reactions: True, cortisol reduces inflammation.
  • (iii) Maintains electrolyte balance, osmosis and blood pressure: False, this is primarily a function of aldosterone (a mineralocorticoid), not cortisol.
  • (iv) Suppresses immune response: True, cortisol has immunosuppressive effects.
  • (v) Stimulates RBC production: False, erythropoietin (not cortisol) stimulates RBC production.
• Option Analysis:
  • (1) iii only: Correct, as only (iii) does not correspond to cortisol’s functions.
  • (2) iv only: Incorrect, (iv) is a true function.
  • (3) i and ii only: Incorrect, both (i) and (ii) are true.
  • (4) iii and iv only: Incorrect, (iv) is true.
• Conclusion: The correct answer is (1) iii only, as maintaining electrolyte balance is not a primary function of cortisol.
