Question

How is a nerve impulse similar to an electrical signal and how does it move along

a neuron?

Answer 1

Answer:

Axons pass the nerve impulses on to other cells. ... The axon is covered with a myelin sheath, a fatty layer that insulates the axon and allows the electrical signal to travel much more quickly. The node of Ranvier is any gap within the myelin sheath exposing the axon, and it allows even faster transmission of a signal.
