What is saltatory conduction of the nerve impulse?

Explanation

### Step-by-Step Solution:

1. **Definition of Saltatory Conduction**: Saltatory conduction refers to the process by which nerve impulses are transmitted along myelinated nerve fibers in a jumping manner.

2. **Myelinated Nerve Fibers**: Myelinated nerve fibers are those that are encased in a protective layer known as the myelin sheath. This sheath acts as an insulator, preventing the loss of electrical signals.

3. **Nodes of Ranvier**: Between segments of the myelin sheath, there are small gaps known as the Nodes of Ranvier. These nodes are crucial for the process of saltatory conduction.
