By sterelogical technique with application of a test system, a quantitative investigation of the normal rat myocardium has been performed at light and electron microscopic levels. Comparative volume and superficial density of different structures have been determined, as well as secondary (calculated) indices of volumetric and superficial-volumetric relations have been obtained. Semi-thin sections demonstrate quantitative characteristics of parenchymatous-stromal-microcirculatory interrelations, while electronograms demonstrate quantitative indices and interrelations of cardiomyocytic ultrastructures. The ratio of superficial myocardial structures to their volume gives an objective information on functional morphology of the cardiac muscle.
