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 a crucial part of the nervous system that consists of two main components: the brain and the spinal cord.

2. **Identifying the Components**:
- The brain is located within the cranium (the part of the skull that encases the brain) and is responsible for processing information and regulating bodily functions.
- The spinal cord extends from the base of the brain and runs down the vertebral column, connecting the brain to the peripheral nervous system.

3. **Evaluating the Options**:
- **Option 1**: Brain, spinal cord, somatic neural system - Incorrect, as the somatic neural system is part of the peripheral nervous system, not the CNS.
- **Option 2**: Autonomic neural system, brain, somatic neural system - Incorrect, as both the autonomic and somatic systems are parts of the peripheral nervous system.
- **Option 3**: Brain, spinal cord, somatic neural system, autonomic neural system - Incorrect, as this option includes components that are not part of the CNS.
- **Correct Option**: Brain and spinal cord - This is the only correct answer as it accurately lists the components of the CNS.

4. **Conclusion**:
- The central nervous system is composed solely of the brain and spinal cord. Therefore, the correct answer to the question is "brain and spinal cord."
