Which of the following correctly defines the components of the peripheral neural system?

Options

A. Brain + Spinal cord + Somatic neural system
B. Somatic neural system + Automatic neural system
C. Spinal cord + Somatic neural system
D. Spinal cord + Somatic neural system + Automatic neural system

Answer

To solve the question regarding the components of the peripheral neural system, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Nervous System**:
- The nervous system is divided into two main parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
- The CNS consists of the brain and spinal cord.

2. **Identify the Components of the Peripheral Nervous System**:
- The PNS is primarily composed of two systems:
- **Somatic Nervous System**: This system controls voluntary movements and transmits sensory information to the CNS.
- **Autonomic Nervous System**: This system regulates involuntary bodily functions and is further divided into:
- **Sympathetic Nervous System**: Prepares the body for stressful or emergency situations.
- **Parasympathetic Nervous System**: Conserves energy and restores the body to a state of calm.

3. **Evaluate the Given Options**:
- The options provided in the question include combinations of the brain, spinal cord, somatic nervous system, and autonomic nervous system.
- Since the brain and spinal cord are components of the CNS, they do not belong to the PNS.

4. **Select the Correct Definition**:
- The correct definition of the components of the Peripheral Nervous System includes the somatic nervous system and the autonomic nervous system.
- Therefore, the correct answer is the option that includes both the somatic and autonomic nervous systems without including the brain or spinal cord.

### Conclusion:
The correct option that defines the components of the Peripheral Neural System is the one that includes the **somatic nervous system and autonomic nervous system**.
