B. Secreted from adrenal medulla and increases heart beat
C. Secreted from adrenal medulla and decreases heart beat
D. Secreted from pancreas and increases heart beat

Answer

To answer the question "Epinephrine is," we need to analyze the options provided and understand the characteristics of epinephrine.

### Step-by-Step Solution:

1. **Identify the Source of Epinephrine**:
- Epinephrine, also known as adrenaline, is a hormone produced by the adrenal glands. The adrenal glands consist of two parts: the adrenal cortex (outer layer) and the adrenal medulla (inner layer).
- **Hint**: Remember that hormones can originate from different glands in the body.

2. **Determine the Specific Origin**:
- Epinephrine is specifically secreted from the adrenal medulla, not the pancreas. The pancreas primarily secretes insulin and glucagon.
- **Hint**: Differentiate between the hormones produced by the adrenal glands and those produced by the pancreas.

3. **Understand the Function of Epinephrine**:
- Epinephrine is often referred to as the "emergency hormone" or "fight or flight hormone." It is released during stressful situations and prepares the body for rapid action.
- **Hint**: Think about what happens to your body in a stressful situation; this will help you recall the effects of epinephrine.

4. **Analyze the Effects of Epinephrine**:
- One of the primary effects of epinephrine is to increase heart rate, which helps pump more blood to muscles and vital organs during emergencies.
- **Hint**: Consider how your body reacts when you are scared or excited; this reaction is largely due to epinephrine.

5. **Evaluate the Options**:
- The options provided are:
1. Secreted from pancreas and decreases heartbeat
2. Secreted from adrenal medulla and increases heartbeat
3. Secreted from adrenal medulla and decreases heartbeat
4. Secreted from pancreas and increases heartbeat
- Based on our analysis, the correct statement is that epinephrine is secreted from the adrenal medulla and increases heartbeat.
- **Hint**: Cross-reference each option with the information you have gathered about the source and function of epinephrine.

6. **Select the Correct Answer**:
- Therefore, the correct answer is option 2: "secreted from adrenal medulla and increases heartbeat."
- **Hint**: Always double-check your final answer against the question to ensure it aligns with the information provided.

### Final Answer:
Epinephrine is secreted from the adrenal medulla and increases heartbeat.
