Resting membrane potential Nerve Electrical activity 1

Unlock the mystery behind the Resting Membrane Potential (RMP) — the foundation of all electrical activity in excitable cells such as neurons and muscle fibers. In this video, we’ll explore: The ionic basis of resting membrane potential The roles of sodium (Na⁺), potassium (K⁺), and chloride (Cl⁻) ions How the Na⁺/K⁺ pump maintains cellular polarization The significance of electrochemical gradients in nerve and muscle physiology By the end of this lesson, you’ll understand how the delicate balance of ion movement across the membrane creates the electrical stability necessary for action potentials and cellular communication.
