Action Potential Physiology (Part 2)

The video tutorial explains the process of action potential in neurons, focusing on the movement of sodium and potassium ions across the cell membrane. It covers depolarization, repolarization, and hyperpolarization phases, highlighting the role of voltage-gated channels. The tutorial also discusses the propagation of action potential along the axon to the axon terminal, where neurotransmitters are released into the synapse. A graph illustrating voltage changes during these phases is also explained.

What is hyperpolarization and how does it occur?

How does the sodium-potassium pump contribute to the restoration of resting membrane potential?

What is the significance of the action potential in neuron communication?
