Action Potential

Real World Example

Imagine you’re in a crowded room, trying to get someone's attention, and you suddenly shout to break through the noise. This is similar to an action potential in a neuron, where a sudden change in charge allows a nerve impulse to stand out amidst the constant background activity of the nervous system. Just like your shout creates a momentary spike in volume to convey your message, the action potential is a rapid reversal of charge across a neuron’s membrane that allows nerve signals to be transmitted with clarity and urgency.
