Assertion :- Catecholamines (adrenaline) are emergency hormones.
Reason:- Catecholamines are released from adrenal cortex

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Understand the Assertion
The assertion states that "Catecholamines (adrenaline) are emergency hormones."
- Catecholamines, which include adrenaline (also known as epinephrine) and noradrenaline (norepinephrine), are indeed classified as emergency hormones. They are released during stressful situations and prepare the body for a "fight or flight" response. This includes increasing heart rate, blood pressure, and energy availability.

### Step 2: Understand the Reason
The reason states that "Catecholamines are released from the adrenal cortex."
- This statement is incorrect. Catecholamines are actually produced and released from the adrenal medulla, which is the inner part of the adrenal gland. The adrenal cortex, on the other hand, produces different hormones such as cortisol and aldosterone.

### Step 3: Evaluate the Relationship Between Assertion and Reason
- The assertion is true: Catecholamines are indeed emergency hormones.
- The reason is false: Catecholamines are released from the adrenal medulla, not the adrenal cortex.

### Conclusion
Since the assertion is true and the reason is false, the correct answer to the question is that the assertion is correct, but the reason is incorrect.

### Final Answer
Assertion is true; Reason is false.
