What is the structure of a myelin sheath?

Hello there!!

Explanation:

The myelin sheath is a fatty substance which surrounds and insulates neuron axons (i.e. it does not allow potassium or sodium ions to pass through it).The myelin sheath is a protective covering that surrounds fibres called axons, the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed of protein and lipids.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.
