The axon is the long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.
These are like local roads that bring traffic to the highway. They receive information from other neurons and transmit it towards the cell body.
This is like an express lane on our highway. It wraps around parts of the axon, allowing electrical impulses to move more quickly.
This is like the exit ramp at the end of our highway. It's where signals leave one neuron and move towards another.
