Topographic-anatomical features of unpaired branches of the aortal abdominal part at the early period of human ontogenesis

Abstract

A morphological precondition of occurrence of variants in the structure and congenital developmental defects of the unpaired visceral branches of the aortal abdominal part is the effect of damaging factors on morphogenesis during embryonic period and in the middle of the pre-fetal period of human ontogenesis. On the basis of our studies a new solution of the issue concerning morphogenesis of the unpaired branches of the aortal abdominal part was suggested. It assumes a comprehensive examination of peculiarities of the laying and dynamics of the unpaired visceral branches of the aortal abdominal part during the whole prenatal period of human ontogenesis and neonates.
