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.

hope this helps,have a great day!!

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
