WebFigure 5 shows a diagram of how calcium activates the cardiac muscle cell to contract. There are three pools of Ca 2+ that are important to the cardiac muscle cell: the extracellular fluid, the SR, and the cytoplasm. Only Ca 2+ in the latter compartment is able to bind with the troponin-binding sites and initiate contraction. During an action potential, … http://www.cvphysiology.com/Cardiac%20Function/CF020
Webcomponents of the myocyte are present. Given that in DCM myocyte loss is occurring, the unanswered question is whether these antibod-ies are the cause of myocyte death or are noth-ing more than a secondary phenomenon. Some forms of cardiomyopathy which are diYcult to classify may also belong in the DCM group. Patients may present with very WebThe cardiac myocyte is a specialized striated muscle cell that is approximately 25 μ in diameter and about 100 μ in length. They form a branching network of cells that are connected by intercalated discs. The myocyte is composed of bundles of myofibrils that contain myofilaments.
