Expert Solution
Step 1

Membrane potential is defined as a potential gradient that causes ions to flow passively in one direction: positive ions are drawn to the 'negative' side of the membrane, while negative ions are drawn to the 'positive' side. Physiologically, the membrane potential is in charge of transmitting messages to and from the central nervous system(CNS). It is also crucial in cellular biology since it demonstrates how cell biology is intimately linked to electrochemistry and physiology.
