Web19 Oct 2024 · This rectifier current is what is ultimately responsible for the contraction of cardiac muscle, as this potassium efflux initiates a cascade in which calcium ions bind to active sites on cellular contractile proteins (e.g., actin, troponin) and cajole them into action. Web23 Feb 2024 · Action potentials in muscle, initiated by depolarization by a nerve impulse and depolarization of the muscle fibre, require the rapid movement of inorganic ions through transmembrane ion channels. The action potential results in the release of calcium ions from the sarcoplasmic reticulum (SR), leading to contraction of the myofibrils.
