The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire, …
The myelin sheath is a protective membrane that wraps around part of certain nerve cells. Myelin also affects how fast signals travel through those nerve cells.
