What is significance of saltatory conduction of nerve impulses?

Explanation

### Step-by-Step Solution:

1. **Definition of Saltatory Conduction**:
- Saltatory conduction refers to the process by which nerve impulses jump from one node of Ranvier to another along myelinated axons. The myelin sheath acts as an insulator and prevents the loss of electrical charge.

2. **Mechanism of Saltatory Conduction**:
- In myelinated axons, there are gaps known as nodes of Ranvier where the axonal membrane is exposed. When a nerve impulse travels, it does not propagate continuously along the entire length of the axon. Instead, it "jumps" from one node to the next, which significantly speeds up the transmission of the impulse.
