Webb1 juni 2007 · [PDF] Cardiac muscle physiology Semantic Scholar The structure of the cardiac myocyte, the generation and spread of thecardiac action potential, the process of excitation-contraction coupling, and the metabolism and energetics of the heart are described. The heart muscle is remarkable. Cardiac muscle tissue has autorhythmicity, the unique ability to initiate a cardiac action potential at a fixed rate – spreading the impulse rapidly from cell to cell to trigger the contraction of the entire heart. This autorhythmicity is still modulated by the endocrine and nervous systems. There are two types of cardiac muscle cell: cardiomyocytes which have the ability to contract easily, and modified cardiomyocytes the pacemaker cells of the conducting system. The cardiom…
