Your nervous system is the fastest communication network in your body.
Electrical signals called action potentials travel through myelinated neurons using a process known as saltatory conduction.
Because of this, nerve signals can move at speeds of up to 120 meters per second — faster than a racing car.
This is why your body reacts instantly, even before your brain fully processes pain.
👉 Watch Part 2 to understand why pain is felt after damage happens.
