C)relative refractory loop.
D)sodium equilibrium potential.

Question

Quizplus · Accepted Answer

Repolarization of a neuron is achieved through a negative feedback loop, where the influx of positively charged ions (usually sodium) during depolarization triggers the opening of voltage-gated potassium channels, allowing the efflux of positively charged potassium ions from the cell. This efflux of positively charged potassium ions re-establishes the negative membrane potential, therefore repolarizing the cell.
