Myocyte vs muscle fiber
WebJan 17, 2024 · The myocardium, or cardiac muscle, is the thickest section of the heart wall and contains cardiomyocytes, the contractile cells of the heart. As a type of muscle tissue, the myocardium is unique among all other muscle tissues in the human body. The thickness of the myocardium determines the strength of the heart’s ability to pump blood. WebThe muscular system consists of numerous muscles that contribute in the movement of the body and certain movements occurring involuntarily within the body like the pumping …

The action potential of the contractile cardiac muscle fiber (Fig 5) is longer in duration (200-220 msec) than that seen in skeletal muscle (2 msec). In cardiac cells there ... WebThe myocyte loss coupled with fibrosis in the form of interstitial collagen deposition results in decreased compliance, which along with the accompanying cardiac dilation, results in overload of remaining myocytes. This keeps the process going, with compensation by continuing myocyte hypertrophy.
