The Nervous System, Part 2 - Action! Potential!: Crash Course A&P

The video explains how neurons communicate through action potentials, which are electrical impulses that travel along neurons. It covers the basics of electricity in the body, the resting membrane potential, and how action potentials are generated and propagated. The video also discusses the frequency and speed of action potentials, influenced by factors like the myelin sheath. Finally, it introduces future topics and the Crash Course Kids channel.
