The sodium-potassium pump maintains the neuron's resting membrane potential by actively pumping sodium ions out of the cell and potassium ions into the cell, creating a negative internal charge. This helps to establish the typical resting potential of -70mV in neurons.

What system keeps the neuron at resting potential?

The sodium-potassium pump is responsible for maintaining the resting membrane potential of a neuron by actively pumping sodium ions out of the cell and potassium ions into the cell, against their concentration gradients. This creates an imbalance of ions across the membrane, contributing to the resting potential of the neuron.

Why does the membrane have to pump sodium and potassium across the membrane and keeps pumping it?

The membranes of nerve Cells use the Sodium/Potassium pump system to charge It's membranes, for a reversal of this condition constitutes the discharge of this Action Potential - 'keeps pumping it' refers to recharging the membrane's Action Potential.
