Question

Choose the correct sequence of events on short term endocrine response to stress:

• A. A, B, C, D, E
• B. A, C, B, D, E
• C. B, A, D, C, E
• D. B, A, C, D, E

Hint:

Stress starts “Outside” (Stressor) and moves to the “Brain” (Hypothalamus) before reaching the “Body” (Adrenal).

Answer 1

The Correct Option is D

Step 1: Concept
The short-term stress response (Fight-or-Flight) is mediated by the sympathomedullary (SAM) system. Step 2--3: Analysis
A stressor occurs (B). The hypothalamus perceives it (A). Sympathetic centres in the spinal cord are activated (C). Signals reach the adrenal medulla (D). Adrenaline and nor-adrenaline are released (E).

Step 4: Conclusion
The sequence is B $\to$ A $\to$ C $\to$ D $\to$ E.

Final Answer: (D)
