Options

A. Cranial nerves
B. Brain
C. Spinal nerves
D. Both (1) & (2)

Answer

To solve the question "Which among the following is not a part of PNS?" we need to analyze the options provided and understand the structure of the nervous system.

### Step-by-Step Solution:

1. **Understand the Nervous System Structure**:
- The human 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.
- The PNS consists of all the nerves that branch out from the CNS, including cranial nerves and spinal nerves.

2. **Identify the Options**:
- The options given are:
- A) Cranial nerves
- B) Brain
- C) Spinal nerves
- D) Both A and B

3. **Analyze Each Option**:
- **Cranial Nerves**: These are part of the PNS as they emerge directly from the brain and innervate various parts of the body.
- **Brain**: This is part of the CNS, not the PNS.
- **Spinal Nerves**: These are also part of the PNS as they emerge from the spinal cord and connect to the rest of the body.
- **Both A and B**: Since cranial nerves are part of the PNS, this option cannot be correct.

4. **Conclusion**:
- The only option that is not part of the PNS is the **Brain**. Therefore, the correct answer is **B) Brain**.

### Final Answer:
B) Brain
