Which of the following neural system relays impulses from CNS to skeletal muscles?

Options

A. Somatic neural system
B. Sympathetic neural system
C. Parasympathetic neural system
D. Peripheral neural system

Answer

To answer the question, "Which of the following neural systems relays impulses from the CNS to skeletal muscles?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Central Nervous System (CNS)**:
- The CNS consists of the brain and spinal cord. It is responsible for processing information and sending signals to different parts of the body.

2. **Identifying the Types of Neural Systems**:
- **Somatic Neural System**: This system is responsible for voluntary control of body movements via skeletal muscles. It relays impulses from the CNS to skeletal muscles.
- **Sympathetic Neural System**: Part of the autonomic nervous system, it prepares the body for 'fight or flight' responses and does not directly control skeletal muscles.
- **Parasympathetic Neural System**: Also part of the autonomic nervous system, it manages 'rest and digest' functions and does not control skeletal muscles.
- **Peripheral Neural System**: This term generally refers to all nerves outside the CNS but does not specifically relay impulses to skeletal muscles.

3. **Analyzing the Options**:
- **Option A: Somatic Neural System** - Correct. It relays impulses from the CNS to skeletal muscles.
- **Option B: Sympathetic Neural System** - Incorrect. It does not relay impulses to skeletal muscles.
- **Option C: Parasympathetic Neural System** - Incorrect. It does not relay impulses to skeletal muscles.
- **Option D: Peripheral Neural System** - Incorrect. While it encompasses nerves that may include those to skeletal muscles, it is not specific to relaying impulses from the CNS to skeletal muscles.

4. **Conclusion**:
- The correct answer is **A: Somatic Neural System**.
