After sympathetic stimulation, which type of activities are not present in human being

Options

A. Tachycardia
B. Bronchodilation
C. Micturition
D. Semen Ejaculation

Answer

**Step-by-Step Solution:**

1. **Understanding Sympathetic Stimulation**: The sympathetic nervous system is part of the autonomic nervous system that prepares the body for 'fight or flight' responses during stressful situations. It increases heart rate, dilates airways, and inhibits non-essential functions.

2. **Identifying Activities Affected by Sympathetic Stimulation**:
- **Heart Rate**: Sympathetic stimulation increases heart rate to supply more oxygen to muscles.
- **Bronchial Dilation**: The airways dilate to improve airflow to the lungs, which is a response to sympathetic stimulation.
- **Micturition**: This refers to the process of urination. During sympathetic activation, this process is inhibited as the body prioritizes other functions.
- **Semen Ejaculation**: This is also facilitated by sympathetic stimulation, as it is part of the reproductive response.

3. **Conclusion**: Among the options provided, micturition is the activity that does not occur during sympathetic stimulation. Therefore, the correct answer is that after sympathetic stimulation, micturition is not present in human beings.

**Final Answer**: Micturition is not present after sympathetic stimulation.
