<h2>Sodium channels </h2>

Explanation:

Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli

Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
Action potential is an efficient signaling process by which distantly located cells communicate to each other
Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
