Why does an impulse run much faster along a thick myelinated fibre than along a thin non-myelinated one?
The myelin makes the membrane more permeable to Na+ everywhere.
The myelin makes the impulse by itself, so no ions are needed.
The myelin insulates the axon, so the impulse jumps from node to node.
The myelin carries the neurotransmitter along the axon.
