Question

Question 36 The characteristic plateau in the action potential developed during cardiac muscle contraction is O caused by the removal of calcium ions from the sarcolplasmic reticulum and their transfer to the interstitial fluid outside of the cell Odue to the opening of fast sodium channels in the sarcolemma o produced by the tendency of cardiac muscle fibers to repolarize very quickly 0 the result of the gradual opening of voltage gated calcium channels and the slow movement of calcium ions to the inside of the cells

Explanation / Answer

Answer 36. The right option is the result of the gradual opening ...... inside of the cells.

This Plateau phase is sustained by bringing a balance between the inward movement of the Ca2+ ions and outward mo ement of K+ ions.
