Abstract
The aim of this study was to establish the origins of development and to examine the structure of the intraventricular formations of the human heart during the intrauterine development. In the study of the serial sections of 57 human embryos of 6-70 mm parietococcygeal length, no subdivision of ventricular myocardium on external, middle and inner layers was detected. This means that not only the carneal trabecules but also the papillary muscles are formed by the bundles of cardiomyocytes originating from the whole thickness of the myocardium. The multilevel pattern of trabecular network of cardiac ventricles at the early stages of embryogenesis is described. It is suggested that the orientation of the carneal trabecules within the trabecular network is associated with the structure of the cardiac tube, which gives rise to the heart during development.
