Comparing the somatic nervous system with the autonomic nervous system, which of the following statements is true?

Options

A. Autonomic nervous system produces involuntary movement in skeletal muscle
B. Somatic nervous system produces voluntary movement in glands and smooth muscle
C. Autonomic nervous system produces voluntary movement in smooth muscle and glands
D. Autonomic nervous system produces involuntary movement in smooth muscle, viscera and glands

Explanation

To compare the somatic nervous system (SNS) with the autonomic nervous system (ANS) and identify the true statement, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Somatic Nervous System (SNS)**:
- The SNS is responsible for voluntary movements and is primarily associated with the control of skeletal muscles.
- It allows conscious control over muscle movements and is involved in reflex actions.

2. **Understand the Autonomic Nervous System (ANS)**:
- The ANS controls involuntary bodily functions and regulates smooth muscles, cardiac muscles, and glands.
- It is divided into sympathetic and parasympathetic divisions, which manage involuntary actions such as heart rate, digestion, and respiratory rate.

3. **Evaluate the Statements**:
- **Statement 1**: "The autonomic nervous system produces involuntary movement in skeletal muscle."
- This is **incorrect**. The ANS does not control skeletal muscles; it controls smooth and cardiac muscles.

- **Statement 2**: "The somatic nervous system produces voluntary movement in glands and smooth muscles."
- This is **incorrect**. The SNS does not control glands and smooth muscles; it primarily controls voluntary movements of skeletal muscles.

- **Statement 3**: "The autonomic nervous system produces voluntary movement in smooth muscles and glands."
- This is **incorrect**. The ANS is responsible for involuntary movements, not voluntary.

- **Statement 4**: "The autonomic nervous system produces involuntary movement in smooth muscles and viscera and glands."
- This is **correct**. The ANS indeed controls involuntary movements in smooth muscles, cardiac muscles, and glands.

4. **Conclusion**:
- The true statement among the options provided is that the autonomic nervous system produces involuntary movement in smooth muscles, viscera, and glands.

### Final Answer:
The correct statement is: "The autonomic nervous system produces involuntary movement in smooth muscles and viscera and glands."
