The heterogeneity of the myocardial mitochondrial apparatus and the mechanisms of its formation in the early ontogeny of rats

The quantitative morphological characteristics of three types of mitochondria in adult rat cardiac myocytes are presented. The existence of two mitochondrial functional modes depending on the intracellular localization and condition of the myofibrillar apparatus has been revealed. The quantitative correlation between the types of these organelles during ontogenesis has been estimated.
