Detailed Solution

Sequence of events occuring when a neuron is stimulated.

(b) Influx of Na⁺(Sodium ions rush into the neuron due to the opening of voltage-gated sodium channels in the axon membrane)
(d) Depolarization (The influx of Na⁺ causes the inside of the neuron to become more positive)
(c) Efflux of K⁺ (Potassium ions begin to leave the neuron due to the opening of voltage-gated potassium channels)
(a) Repolarization (The efflux of K⁺ causes the inside of the neuron to become more negative again, returning to its resting membrane potential)
