SUMMARY
Action potentials (APs) propagate along large myelinated neurons through the active spread facilitated by voltage-gated cation channels. While passive spread of depolarization is effective in small myelinated and large unmyelinated neurons, large myelinated neurons rely on the rapid conduction enabled by these channels. The discussion emphasizes the importance of understanding both passive and active mechanisms in neuronal signaling, particularly in the context of myelination.
