Do myelin sheaths increase speed

WebAs explained by the answers there, the reason saltatory conduction in myelinated neurons is faster than non-myelinated conduction is because the capacitance of the membrane is lowered by reducing the number of channels (Channel density) or equivalently, increasing the spacing between channels.
