The features of human heart internal relief structure in prenatal ontogenesis
Abstract
We have reviewed the development of internal relief of 101 human hearts during prenatal ontogenesis. It was used a macroscopic, immunohystochemical research methods, which enabled us to trace the processes of vessel’s development, proliferation of cardiac wall cells, heteromorphy of its structure in various stages of development. The data indicate the involvement of cardiogel, primary cardiomyocytes, as well as mesenchymal cells in the development and statement of the structural components, which form the internal relief of the heart chambers. The process of heart wall’s delamination is a separate morphological mechanism. Delamination plates are embryo material for the formation of tendinous chords, papillary muscles and muscle trabecula. Process of forming of the internal structures of relief occurs during the prenatal period of 5-20 weeks ontogenesis. One of the first parts of the heart, in which the process of papillary-trabecular apparatus forming occurs, is the atrium’s wall.
