Myelinated Nerve Fiber (Noun)
Meaning
A nerve fiber encased in a sheath of myelin.
Classification
Nouns denoting body parts.
Examples
- A myelinated nerve fiber is a nerve fiber that has a myelin sheath surrounding the axon, facilitating quicker transmission of electrical impulses.
- The structure of a myelinated nerve fiber includes a myelin sheath that is formed from the lipids and proteins of the myelin-producing cells.
- Myelinated nerve fibers play a crucial role in transmitting signals between different parts of the nervous system and are characterized by their rapid conduction velocity.
- In the peripheral nervous system, myelinated nerve fibers are classified as either A fibers or B fibers based on their conduction velocity and diameter.
- The demyelination of a myelinated nerve fiber can lead to significant damage and disruption of normal nerve function and is a characteristic of certain neurodegenerative disorders.
