ion permeance and action potential

Three-panel diagram showing the diffusion of chloride and potassium ions across a semipermeable membrane. Panel A illustrates movement driven by a concentration gradient, panel B shows both concentration gradient and opposing electrostatic force, and panel C depicts equilibrium potential where forces balance and ion flow is stable. Chloride ions are marked in blue, potassium ions in red, with direction arrows indicating ion movement.
