Neuronal Polarization, Action Potentials, and Myelination - Week 11

This episode dives into the mechanics of neuronal function, from resting membrane potential and the all-or-nothing action potentials to the critical role of myelination by Schwann cells and oligodendrocytes. Learn how signal transmission is optimized and what happens when conditions like multiple sclerosis disrupt this process. We also highlight the support roles of astrocytes and ependymal cells in maintaining neural health.
