Select the correct statement from the following.

Options

A. Nissi's granules are found in cell body and dendrities
B. Axonal membrane is more permeable to `Na^(+)` at resting state.
C. The autonomic nervous system transmits impulses from the CNS to the voluntary muscules and organs of the body
D. Typical neurous in PNS are non myelinated

Answer

To solve the question of selecting the correct statement regarding neurons from the provided options, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Components of Neurons**:
- Neurons are the basic structural and functional units of the nervous system.
- They consist of three main parts: the cell body (soma), dendrites, and axon.

2. **Analyzing the Statements**:
- **Statement 1**: "Nissl's granules are found in cell body and dendrites."
- Nissl's granules, which are composed of rough endoplasmic reticulum and ribosomes, are indeed found in the cell body and dendrites of neurons. This statement is likely to be correct.

- **Statement 2**: "Axonal membrane is more permeable to sodium at resting state."
- At resting state, the axonal membrane is more permeable to potassium ions, not sodium ions. Therefore, this statement is incorrect.

- **Statement 3**: "There are two parts of the human neural system."
- The human nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). This statement is incomplete as it does not mention the two parts of the PNS (somatic and autonomic nervous systems) correctly.

- **Statement 4**: "Typical neurons in PNS are non-myelinated."
- This statement is incorrect because while some neurons in the PNS can be non-myelinated, many are myelinated (e.g., those that form the myelin sheath around axons).

3. **Conclusion**:
- After analyzing all the statements, the first statement is the only correct one: "Nissl's granules are found in cell body and dendrites."

### Final Answer:
The correct statement is: **Nissl's granules are found in cell body and dendrites.**
