Which of the following is not a sympathetic effect?

Options

A. Increased blood pressure
B. Increased storage of glycogen from glucose
C. Increased heart rate
D. Increased constriction of the blood vessels

Explanation

To determine which of the following is not a sympathetic effect, we need to analyze the options provided in relation to the functions of the sympathetic nervous system.

### Step-by-Step Solution:

1. **Understand the Sympathetic Nervous System**:
- The sympathetic nervous system is responsible for the "fight or flight" response. It prepares the body to respond to stressful situations.

2. **Review the Options**:
- **Option 1**: Increased blood pressure
- **Option 2**: Increased storage of glycogen from glucose
- **Option 3**: Increased heart rate
- **Option 4**: Increased constriction of blood vessels

3. **Analyze Each Option**:
- **Increased blood pressure**: This is a sympathetic effect as it prepares the body for action.
- **Increased storage of glycogen from glucose**: This is not a sympathetic effect. Instead, it is associated with the parasympathetic nervous system, which promotes rest and energy storage.
- **Increased heart rate**: This is a sympathetic effect, as it helps in preparing the body for quick responses.
- **Increased constriction of blood vessels**: This is also a sympathetic effect, as it helps redirect blood flow to essential organs during stress.

4. **Identify the Correct Answer**:
- The only option that is not a sympathetic effect is **Option 2: Increased storage of glycogen from glucose**.

### Final Answer:
**The option that is not a sympathetic effect is: Increased storage of glycogen from glucose.**
