Vedclass · Answer

(D) The action potential in a neuron is generated by the rapid influx of $Na^{+}$ ions into the cell.When a stimulus is applied to a neuron,the voltage-gated $Na^{+}$ channels open,allowing $Na^{+}$ ions to rush into the intracellular space.This influx causes depolarization of the neuronal membrane,shifting the membrane potential from its resting state (approximately $-70 \ mV$) to a positive value (approximately $+30 \ mV$ to $+45 \ mV$).Therefore,the correct answer is $Na^{+}$.

The action potential in a neuron is generated by which of the following?

What occurs during the repolarization of a nerve fiber?

When a neuron is in resting state,$i.e.$,not conducting any impulse,the axonal membrane is

$A$: Presence of myelin sheath increases the rate of conduction of nerve impulse.
$R$: Ionic channels are absent in the area covered by myelin sheath; therefore,depolarization occurs only at the nodes of Ranvier,resulting in saltatory or jumping conduction.
