MODERN VIEW ON THE MORPHOFUNCTION OF THE HEART AND INTRACARDIAC NERVOUS STRUCTURES

Abstract

Introduction. Over the past 10 years, there has been a high mortality rate from cardiovascular system pathologies associated with the autonomic nervous system. Mortality from heart pathology and its complications is mainly observed among the working-age population. At the same time, the relationship between the cardiac conduction system and the autonomic nervous system, as well as their role in regulating the stable functioning of the heart, occupy a significant place in modern scientific hypotheses proposed by a number of researchers. In this regard, research in this area remains highly relevant. Aim: To analyze the scientific literature on the morphofunctional basis of the regulation of cardiac activity and intracardiac nervous structures. Search Strategy: The search for articles was conducted using the databases of PubMed, Google Scholar, Embase, and the Cochrane Library, as well as data from domestic scientific publications. The search covered a 10-year period (2014– 2024). A total of 71 scientific publications were analyzed. Results. As a result of the study, explanations are provided regarding the relevance of morphological research on the cardiovascular system, along with modern scientific conclusions on the morphological function of the heart's nervous structures. Conclusion. The significance of morphological structures, including intracardiac nerve plexuses, nodes, and fibers, which play a crucial role in the stable functioning of the heart, has been established.
