The morphology of the elements of the myocardial contractile apparatus question and research prospects
Background. Over the past 50 years, specific methods for studying the ultrastructure of the heart have been rapidly developed. The complex interaction of various research methods makes it possible to more accurately form a representation of the spatial structure of the components of the myocardial contractile apparatus. Objective. To conduct a content analysis of the results of the study of the composition of the myocardial contractile apparatus. Conduct a broad analysis of literary references and form an understanding of the spatial structure of the components of the myocardial contractile apparatus in the prospect of research at different levels of cell organization. Methods. Processing of information sources was carried out by the method of complex meta-analysis of data analysis. Results. The morphological characteristics of the myocardial contractile apparatus include a number of broad profile elements. The system of composite elements of the contractile apparatus of cardiomyocytes is the most formed and developed in the structure of the cytoplasmic complex of organelles in the group of contractile cardiomyocytes. The complex of the contractile apparatus is represented by myofibrils, each of which consists of thousands of sarcomeres telophragm connected in series, containing actin (thin) and myosin (thick) myofilaments. The main methods for studying the contractile apparatus of the myocardium include how immunohistochemistry and transmission electron microscopy provide an understanding of the structure of components at various levels of organization of histoarchitectonics and ultrastructure of organelles.. The contractile apparatus of the myocardium includes species-specific organelles, which basically belong to a number of basic hardware systems of cardiomyocytes. Conclusion. Immunohistochemical methods should clearly show the localization of individual tipes of elements in the protein structure of the contractile apparatus of the myocardium, and therefore should include in the study methods the use of the following immunohistochemical markers that can show the configuration of thin and thick myofilaments. The results of analytical review and analysis of information sources on the characteristics of the components of the myofibrillar complex gives a choice of specific research methods and forms a more detailed understanding of the spatial organization of the morphology of the myocardial contractile apparatus.
