How do unmyelinated nerve fibers differ from myelinated nerve fibers?

Show Answers

Exhibit higher excitability levelsLack nodes of RanvierCannot regenerate after injuryAre not surrounded by Schwann cellsTransmit impulses faster

Explanation

Unmyelinated fibers do not possess nodes of Ranvier, which are gaps in the myelin sheath found in myelinated fibers. This structural difference affects their conduction properties.
