[Characteristics of myocardial cholinergic innervation and its species differences].

By means of some neuromorphological and physiological methods, peculiarities of the cardiac cholinergic innervation have been studied in the rabbit, guinea pig, cat, rat and man. The mammalian myocardium (the man including) is heterogeneous in its parasympathetic innervation. There are no terminal cholinergic plexuses in the external and medial layers of the myocardial ventricles, their density is not the same in other myocardial area.

[Age-related changes in the cholin- and adrenergic innervation of the human heart].

The hearts of 35 patients of different age have been studied. The cholinergic innervation reaches full differentiation by the age of 30, its involution begins after 50. The adrenergic innervation is most manifest in children, its involution begins from 30.
