An action potential is propagated down an unmyelinated neuron plasma membrane because the action potential stimulates certain voltage-gated channels adjacent to it. Which channels are they?

Question

Quizplus · Accepted Answer

The correct channels are Na⁺ channels, which in standard notation are referred to as Na+ channels. These sodium channels are crucial for the propagation of action potentials along neurons by allowing the influx of Na+ ions when they open, leading to depolarization of the neuron membrane.
