Diagram of cardiac muscle
WebCardiac excitation-contraction coupling (Cardiac EC coupling) describes the series of events, from the production of an electrical impulse (action potential) to the contraction of muscles in the heart. This process is of vital importance as it allows for the heart to beat in a controlled manner, without the need for conscious input. EC coupling results in the … WebThe cardiac muscle pumps blood through the body and is under involuntary control. Smooth muscle tissue contraction is responsible for involuntary movements in the internal organs. It forms the contractile …
