Cardiac Muscle Cells Histology. Skeletal and cardiac muscle cells are called striated muscle because of the very regular arrangement of their intracellular contractile units sarcomeres at the light microscope LM and electron microscope EM levels. Cardiac muscle cells cardiomyocytes contain the same contractile filaments as in skeletal muscle sarcomeres.
Ventricle wall - histology slide. Cardiac muscle is also striated. Unique to the cardiac muscle are a branching morphology and the presence of intercalated discs found between muscle fibers.
Muscle cells of non-striated muscle tissue are also relaxation and accompanying changes in tension.
Such an arrangement is not seen in smooth muscle cells. Histology of cardiac muscle 1. After these cells migrate from the epiblast layer to the splanchnic layer they become the primary heart field. Skeletal and cardiac muscle cells are called striated muscle because of the very regular arrangement of their intracellular contractile units sarcomeres at the light microscope LM and electron microscope EM levels.
