Destruction of the anterior horn cells of the spinal cord would result in loss of

Options

A. Sensory impulses
B. Voluntary motor impulses
C. Commissural impulses
D. Integrating impulses

Answer

### Step-by-Step Solution:

1. **Identify the Structure**: The question refers to the anterior horn cells of the spinal cord. These cells are located in the anterior gray matter of the spinal cord.

2. **Understand the Function**: The anterior horn cells contain motor neurons. These motor neurons are responsible for sending motor impulses.

3. **Determine the Type of Muscles Affected**: The motor impulses from the anterior horn cells primarily control voluntary muscles, specifically the skeletal muscles.

4. **Analyze the Consequence of Destruction**: If the anterior horn cells are destroyed, the motor neurons would be affected, leading to a loss of motor impulses. This would result in an inability to control voluntary muscles.

5. **Evaluate the Options**:
- **Option A**: Loss of sensory muscles - Incorrect, as sensory functions are not controlled by anterior horn cells.
- **Option B**: Loss of voluntary motor impulses - Correct, as this directly relates to the function of the anterior horn cells.
- **Option C**: Loss of commissural impulses - Incorrect, as commissural impulses are related to interneurons, not motor neurons.
- **Option D**: Loss of integrating impulses - Incorrect, as integrating impulses are not the primary function of the anterior horn cells.

6. **Conclusion**: The destruction of the anterior horn cells would result in the loss of voluntary motor impulses, making option B the correct answer.
