Liver topography in human embryos.

Abstract

Introduction. The study of the development and formation of the liver topography is necessary both to establish the general patterns of liver histogenesis and to identify the processes leading to the occurrence of congenital malformations of the organ. The aim of the study. The purpose of the work is to establish the peculiarities of the structure and morphogenesis of the liver in the intrauterine period of development, in particular, in human embryos. Material and methods. The study of the peculiarities of the liver development in the embryonic period of human ontogenesis was carried out on 20 histological preparations of human embryos (embryos 4.0-13.0 mm long) by the methods of histological examination, production of graphic reconstructions and morphometry.
