Abstract: This article is a document that explains "An Introduction to Resting Potential and Action Potential." The human body is composed of approximately 60 trillion (60 × 10¹²) cells. While most of these are quite similar in size and shape, there are also some that are distinctly different, such as nerve and muscle cells; these cells are quite long, thin, and macroscopically visible. Despite possessing complete genomic information, each cell performs various functions, including organs, nerves, muscles, the brain, and skin. This study examines a very simplified cell model sufficient to explain the resting potential and action potential. The action potential is a fundamental electrochemical process that enables receptors, nerve cells, and muscle tissue to perform their functions. However, for this potential to occur, cells must first be in a resting potential state; this is the starting point for this study. Changes in the electrical potential of the cell membrane are highly regulated and energy-dependent processes that form the basis of neural and muscular activity. The resting potential is a fundamental requirement of life, maintained by maintaining the ionic balance between the cell's internal and external environments. The action potential, on the other hand, is a rapid and transient event that briefly disrupts this balance but plays a critical role in signal transmission. These electrical events, which occur through the conduction of Na⁺ and K⁺ ions across the membrane through voltage-gated channels, last only a few milliseconds but are vital to the organism's information processing capacity. During this process, the cell membrane acts like a capacitor; electrical charges accumulate or discharge as the membrane potential changes. Calculations show that only a very small fraction of ions are required to cross the membrane to generate a resting potential or action potential.
