Saltatory conduction of impulse occurs in

Options

A. liver cells
B. non-myelinated nerve fibres
C. myelinated nerve fibres
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Nerve Fibers**: Nerve fibers can be classified into two types: myelinated and non-myelinated. Myelinated nerve fibers have a protective covering called the myelin sheath, while non-myelinated fibers do not.

2. **Identifying Myelinated Nerve Fibers**: Myelinated nerve fibers are characterized by the presence of the myelin sheath, which wraps around the axon. This sheath is not continuous; there are gaps known as the nodes of Ranvier.

3. **Explaining Saltatory Conduction**: Saltatory conduction refers to the way nerve impulses travel along myelinated fibers. Instead of traveling continuously along the axon, the impulse "jumps" from one node of Ranvier to the next. This jumping action speeds up the conduction of the impulse.

4. **Conclusion**: Since saltatory conduction occurs specifically in myelinated nerve fibers due to the presence of the myelin sheath and nodes of Ranvier, the correct answer to the question is that saltatory conduction of impulse occurs in myelinated nerve fibers.

5. **Final Answer**: The answer is option C: Myelinated nerve fibers.
