Action Potentials

Summary

This video script explains the process of nerve impulse transmission. It details how nerve impulses are not like typical electricity but involve the movement of charged particles across the cell membrane. The script outlines the resting state of a neuron, the depolarization that initiates an impulse, and the subsequent repolarization. It also covers the refractory period, where the neuron cannot immediately fire again, and the role of the sodium-potassium pump in restoring the resting potential, which is crucial for the neuron's energy consumption and the one-directional movement of action potentials.
