Differentiate between Myelinated and non-myelinated nerve fibres

Explanation

### Step-by-Step Solution:

1. **Definition of Myelinated Nerve Fibers**:
- Myelinated nerve fibers are those that are covered with a myelin sheath, which is a fatty layer that insulates the axon and facilitates faster transmission of nerve impulses.

2. **Definition of Non-Myelinated Nerve Fibers**:
- Non-myelinated nerve fibers lack this myelin sheath. As a result, they do not have the insulating properties that myelinated fibers possess.
