[Innervation opf the juxtaglomerular complex (JGC) of the kidney in vertebrates].

On the base of electron microscopic investigations of kidneys, performed on some representatives of vertebrata (fishes, amphibia, reptiles, birds, mammalia) the data on their JGC innervation are presented. In the course of evolution the structure of nervous-muscular, nervous-endocrine and nervous-epithelial contacts becomes more complex. The role of the nervous factor in regulation of the systemic blood flow and water-salt metabolism acquires a greater significance in the process of development.
