An action potential diagram typically depicts a neurons membrane potential over time The graph showcases how the membrane potential rapidly changes from a resting state to a peak and then returns to its resting state Crucially this isnt a static event its a dynamic interplay of ion channels and electrochemical gradients Key Components of the Action Potential Diagram Resting Potential Typically around 70mV representing the neurons stable state before stimulation This state relies on the selective permeability of the membrane to ions particularly potassium K Depolarization Stimulation triggers the opening of voltagegated sodium Na channels Sodium rushes into the cell causing a rapid increase in membrane potential often reaching 30mV Repolarization As sodium channels close voltagegated potassium K channels open allowing potassium to exit the neuron This efflux restores the negative membrane potential Hyperpolarization Often potassium channels remain open slightly longer than needed for repolarization leading to a temporary dip in the membrane potential below the resting potential Refractory Period This period follows the action potential preventing the neuron from firing another action potential immediately This crucial property ensures unidirectional signal transmission Statistics and Expert Insights 2 Studies show that the speed of action potentials can vary
