Watch first, it explains the entire mechanism of generating an action potential, important for the neurons of the Nervous System through the electrochemical gradient of the interior and exterior of the cell.
A resting potential is the difference in charge across the membrane when a neuron is not firing
Neurons generate and conduct electrical signals by pumping positively charged ions (Na+ and K+) across their membrane
The maintenance of a resting potential is an active process (i.e. ATP dependent) that is controlled by sodium-potassium pumps
Explain the meaning of each of these key words
