Webinducing muscle contraction, and perception of all our senses. Action potentials are initiated when depolarizing graded potentials reach threshold potential. This is the specific membrane potential that induces activation of the voltage-gated ion channels responsible for action potentials and is most often the voltage-gated Na+ channel. If a WebPlateau (Phase 2) Phase 2 is characterized by a plateau that prolongs the action potential. This is due to a balance between the outward flow by delayed rectifier potassium channels and inward flow by calcium channels. The L-type calcium channels causing the inward flow of calcium ions also bind to receptors on the sarcoplasmic reticulum (SR ...
