Vedclass · Answer

(A) The action potential in a neuron is primarily generated by the rapid influx of sodium ions $(Na^+)$ into the cell.When a stimulus reaches the threshold level,voltage-gated $Na^+$ channels open,allowing $Na^+$ to rush into the neuron down its electrochemical gradient.This influx causes the membrane potential to change from its resting state (negative) to a positive value,a process known as depolarization.Therefore,the correct answer is $Na^+$.
