Question
How does myelin "insulate" an axon?
It is made of multiple layers of mostly lipids, which are impermeable to ions.
The multiple layers of myelin slow down the diffusion of ions into the axon because it takes the ions a long time to cross each layer before they can diffuse into the axon.
It generates an electrical charge which repels ions from crossing the plasma membrane.
a.It is made of multiple layers of mostly lipids, which are impermeable to ions.
b.The multiple layers of myelin slow down the diffusion of ions into the axon because it takes the ions a long time to cross each layer before they can diffuse into the axon.
c.It generates an electrical charge which repels ions from crossing the plasma membrane.
d. It forms a single, very thick layer around the axon, which slows the diffusion of ions.Explanation / Answer
