$A$ nerve impulse is defined as .........

When a neuron is in resting state $I$ not conducting any impulse,the axonal membrane is :

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

During resting potential,the axonal membrane is polarised. Indicate the movement of $+ve$ and $-ve$ ions leading to polarisation diagrammatically.

In the resting stage of a neuron,the concentration gradient is generated due to:

The mineral necessary for nervous conduction is
