Anatomical peculiarities of the gastroduodenal segment during the fetal period of human ontogenesis.

Abstract

The purpose of research: definition topography and anatomical features a gastroduodenal segment in the fruit period of the person’s ontogenesis. The anatomical trial has bun performed on 56 fetal corpses aged 4-9 months. It has been established that the morphometric parameters of the gastroduodenal segment increase more intensively during the 2nd trimester of the intrauterine development. The angular value between the longitudinal axes of the pyloric part and the body of the stomach changes from on obtuse to an acute angle the latter being conducive to the formation of the angular notch of the stomach. The aboral orientation of the mucous of the pylorus and its muscular layer manifests itself during the 6th month of prenatal development, resulting in the formation of the duodenal sinus. The received data promote adequate interpretation of age features of the gastroduodenal segment and development of diagnostic methods of the person’s ontogenesis in the perinatal the period.
