[Morphological characteristics of tissue components of different layers of the rat myocardium].
The tissue components of the subendocardial, inner and outer intramural layers of the myocardium were examined by morphometry. There was no significant difference in the proportion of cardiomyocytes in the different layers of the myocardium (subendocardium 0.820 +/- 0.007; inner layer 0.713 +/- 0.100; outer intramural layers 0.727 +/- 0.008; subepicardium 0.699 +/- 0.009). The relative surface of cardiomyocytes was maximal in the subepicardium (58.62 +/- 1,18). The magnitudes of the volumetric density and surface of the capillaries decreased from the subepicardial toward the subendocardial layer. The diameter of myocytes in the test layers of the myocardium varied within a wide range.
