Abstract

Nervous apparatuses of the fetal membranes have been studied in white rats on the 18th-19th days of embryogenesis. Experimental hypoxia, novocaine and potassium chloride solutions effect ensure better revealing of the nervous system elements. At supravital staining with mythelene blue and at impregnation with silver nitrate, nervous fibers are revealed in the distal part of the umbilical cord and in the placental chorional plate. In the labyrinth part of the placenta certain nervous terminals are revealed. In the amnion certain nervous fibers and terminals are found both in the connective tissue and in the epithelium. On the omphaloplacenta vessels numerous nervous apparatuses are detected. A conclusion is made that at the end of embryogenesis the fetal membranes in the white rats are abundantly innervated. This demonstrates nervous regulation of the fetal membranes functions and of interrelationships of the fetus and the maternal organism.
