An action potential is propagated down an unmyelinated neuronal plasma membrane because it stimulates voltage-gated ____ channels adjacent to it. (Choose the most accurate answer.) A) Na⁺ B) Ca²⁺ C) K⁺ D) Na⁺and Ca²⁺ E) K⁺and Ca²⁺

Question

Quizplus · Accepted Answer

Action potentials are primarily propagated down unmyelinated neurons through the stimulation of voltage-gated sodium (Na+) channels, which allow for the rapid influx of Na+ ions, leading to depolarization of the membrane.
