Which of the following correctly enlists the Components of the central neural systems ?

Options

A. Brain+spinal cord + somatic neural system
B. Brain+somatic neural system + Autonomic neural system
C. Brain +spinal cord
D. Brain+spinal cord + somatic neural system+Autonomic neural system

Answer

To solve the question regarding the components of the central nervous system (CNS), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Central Nervous System (CNS)**:
- The CNS is primarily composed of two main structures: the brain and the spinal cord. These are the key components responsible for processing information and controlling bodily functions.

2. **Identifying the Options**:
- We need to evaluate the given options to see which one correctly lists the components of the CNS:
- Option 1: Brain + Spinal Cord + Somatic Neural System
- Option 2: Brain + Somatic Neural System + Autonomic Neural System
- Option 3: Brain + Spinal Cord
- Option 4: Brain + Spinal Cord + Somatic Neural System + Autonomic Neural System

3. **Analyzing Each Option**:
- **Option 1**: Incorrect, as it includes the somatic neural system, which is part of the peripheral nervous system (PNS).
- **Option 2**: Incorrect, as it includes both the somatic and autonomic neural systems, which are also part of the PNS.
- **Option 3**: Correct, as it includes only the brain and spinal cord, which are the components of the CNS.
- **Option 4**: Incorrect, as it includes both the somatic and autonomic neural systems, which are not part of the CNS.

4. **Conclusion**:
- The correct answer is **Option 3: Brain + Spinal Cord**. This option accurately reflects the components of the central nervous system.
