Options

A. Hypothalamus
B. Adrenal medulla
C. Adrenal cortex
D. Adrenal – pancreatic complex

Answer

To answer the question "The fight-or-flight response is developed by the hormones of -", we need to identify the hormones responsible for this physiological reaction.

### Step-by-Step Solution:

1. **Understanding the Fight-or-Flight Response**: The fight-or-flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It prepares the body to either confront or flee from the threat.

2. **Identifying the Source of Hormones**: The hormones responsible for the fight-or-flight response are primarily released from the adrenal glands, specifically from the adrenal medulla.

3. **Key Hormones Involved**: The two main hormones released from the adrenal medulla during the fight-or-flight response are:
- **Adrenaline (Epinephrine)**: This hormone increases heart rate, blood pressure, and energy supplies.
- **Noradrenaline (Norepinephrine)**: This hormone also increases heart rate and blood pressure and prepares the body for action.

4. **Understanding the Term "3F Hormones"**: These hormones are often referred to as "3F hormones" because they are released during conditions of:
- **Fear**
- **Fight**
- **Flight**
This indicates their role in emergency situations.

5. **Conclusion**: Therefore, the fight-or-flight response is developed by the hormones of the adrenal medulla, specifically adrenaline and noradrenaline.

### Final Answer:
The fight-or-flight response is developed by the hormones of the adrenal medulla.
