[Development of retroperitoneal connective tissue and its neural apparatus in the prenatal period of human ontogenesis].

Dynamic parallelism of development in neural and fat tissue-fascial formations of the kidneys and pancreas have been studied in the human prenatal ontogenesis. At various stages of embryogenesis, there are certain correlative connections between formation and differentiation of the renal connective tissue structures, that of the pancreas and the development of their intramural apparatus. The greatest concentration of the neural elements is noted in fat tissue at the level of the posterior surface of the pancreatic head, as well as in the facial-fat tissue formations of the inferior pole and the hilus renalis.
