WebDespite its simple histology, electron microscopy of the pericardium reveals surprisingly detailed cytoarchitecture. Mesothelial cells interdigitate and overlap, which facilitates stretching of the mesothelium in diastole and permits changes in surface configuration; mechanical stability is assured by a cytoskeleton of fine filamentous bundles. WebPurkinje fibers are a unique cardiac end-organ. Further histologic examination reveals that these fibers are split in ventricles walls. The electrical origin of atrial Purkinje fibers arrives from the sinoatrial node . Given no aberrant channels, the Purkinje fibers are distinctly shielded from each other by collagen or the cardiac skeleton .
