The analysis and comparison of histostructural and ultrastructural features of systole and diastole of the chick embryo heart at 29-46th stages on Hamburger, Hamilton were carried out. The main differences between the chambers of the embryonic heart by the nature of developmental dynamics of systolic and diastolic gradients, shows geometrical transformation of the walls of the chambers to reduce, described the features of the ultrastructure of sarcomeres, depending on the location of cardiomyocytes.

Проведены анализ и сопоставление гистоструктурных и ультраструктурных особенностей систолы и диастолы сердца у куриных эмбрионов на 29-46-й стадиях по Hamburger, Hamilton. Определены основные различия между камерами эмбрионального сердца, оценены систоло-диастолические градиенты, показаны геометрические перестройки стенки камер для реализации сокращения, описаны особенности ультраструктуры саркомеров в зависимости от локализации кардиомиоцитов.
