General Physiology – Ionic Distribution and Resting Membrane Potential: Understanding the Basics of Cellular Excitability
Introduction
In the realm of general physiology, understanding ionic distribution and the resting membrane potential is fundamental to grasping how excitable tissues like nerves and muscles function. The delicate balance of ions such as sodium (Na⁺), potassium (K⁺), chloride (Cl⁻), and calcium (Ca²⁺) across the cell membrane creates an electrochemical environment that is essential for cellular communication and responsiveness. This article breaks down the core principles behind ionic gradients, the mechanisms that establish the resting membrane potential, and how these contribute to the physiological behavior of cells. Whether you’re a medical student, biology major, or preparing for board exams, this guide offers a clear and concise explanation of one of the most essential topics in physiology.
