Summary The endocardial surfaces were studied by means of the scanning electron microscope. The subendocardial muscle bundles in the heart were separated by deep and spacious grooves. The division of muscle fibres frequently occurs in an X‐figure. The central portion of the figure is always elevated, although its length may vary in different fibres. The striae on the muscular fibres have also been described. Functional significance of the above findings was discussed.
