Vedclass · Answer

(B) In a resting state,the axonal membrane is polarized,meaning the inside is negatively charged relative to the outside. When a stimulus is applied to a nerve fibre,the permeability of the membrane to $Na^+$ ions increases significantly. This leads to a rapid influx of $Na^+$ ions into the cell. As a result,the inside of the membrane shifts from a negative potential to a positive potential. This change in electrical potential is known as depolarization. Therefore,upon stimulation,the inside of the membrane becomes positively charged.

When a nerve fibre is stimulated,the inside of the membrane becomes:

In the resting stage of a neuron,the concentration gradient allows the diffusion of which ions?

Select the correct option for the permeability of the axonal membrane in a resting state for $K^{+}$,$Na^{+}$,and negatively charged proteins.

$A$ : The imbalance in the concentration of $Na^+, K^+$ and proteins generates the resting potential.
$R$ : To maintain the unequal distribution of $Na^+$ and $K^+$,the neurons use electrical energy.

What is resting potential?

The propagation of an action potential during nerve impulse conduction is made possible by the movement of:
