<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
