Hence, the heart has its own autorhythmicity. This autorhythmicity is due toa small percentage of muscle cells that are specialized to generate and conduct action potentials. These cells are called autorhythmic cells and they make up the conduction system of the heart. ...
“beat” even when it’s isolated from the heart and placed in cell culture in the laboratory.If you removed a little piece of muscle from your heart and put it in a dish, you would see it continue to contract.That’s because cardiac muscle cells have something called an action ...
The heart is a muscular organ that forms part of the cardiovascular system. The heart is located in the thoracic cavity, in the region called the mediastinum. The pumping action of the heart caused by depolarization and repolarization ...
The meaning of CARDIAC MUSCLE is the principal involuntary-muscle tissue of the vertebrate heart made up of striated fibers joined at usually branched ends and functioning in synchronized rhythmic contraction.
2.1Cardiac Cells and Major Components of the Cardiac Extracellular Matrix In a mammalian heart, although the exact cellular population can vary from species to species, the major cell types in themyocardiumare cardiomyocytes (CMs), the main constituent ofcardiac muscle, as well as fibroblasts,endothe...

The wall of the heart is called themyocardiumand is primarily composed of muscle cells which produce mechanical force during contraction of the heart. The myocardium also contains specialized muscle cells which are connected into a network (conduction system) that allows an electrical impulse to rapid...
