Injury to nerve in human is not likely to affect

Options

A. Pancreation secretion
B. Cardiac movements
C. Tongue movements
D. Gastrointestinal movements

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which function is not likely to be affected by an injury to a nerve in humans. We need to evaluate the functions associated with different nerves.

2. **Identifying the Nerves**: The vagus nerve is mentioned as a mixed cranial nerve that controls several functions in the body, including those related to the gut, heart, and respiratory system.

3. **Evaluating Each Option**:
- **Pancreatic Secretion**: The vagus nerve does play a role in stimulating pancreatic secretion. Therefore, an injury to the vagus nerve would affect pancreatic secretion.
- **Cardiac Movements**: The vagus nerve also regulates heart functions, so an injury here would impact cardiac movements.
- **Tongue Movement**: Tongue movements are primarily controlled by the glossopharyngeal nerve, not the vagus nerve. Thus, an injury to the vagus nerve would not affect tongue movement.
- **Gastrointestinal Movement**: The vagus nerve innervates parts of the gastrointestinal tract, so an injury would affect gastrointestinal movements.

4. **Conclusion**: Based on the analysis, the function that is not likely to be affected by an injury to the vagus nerve is **tongue movement**.

**Final Answer**: Tongue movement is not likely to be affected by injury to the vagus nerve.
