To answer the question regarding which hormone(s) are referred to as emergency hormones or "fight or flight" hormones, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of "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. This response is primarily controlled by the autonomic nervous system and involves the release of certain hormones.

2. **Identify Key Hormones Involved**:
- The main hormones associated with the "fight or flight" response are adrenaline (also known as epinephrine) and noradrenaline (norepinephrine). These hormones are produced by the adrenal glands.

3. **Function of Adrenaline and Noradrenaline**:
- Adrenaline increases heart rate, dilates air passages, and increases blood flow to muscles, preparing the body for rapid action.
- Noradrenaline works to increase blood pressure and blood sugar levels, further supporting the body's ability to respond to stress.

4. **Conclusion**:
- Therefore, the hormones that are called emergency hormones or "fight or flight" hormones are **adrenaline and noradrenaline**.
