Abstract
It has been established by means of the methods of an anatomical research that a
ring-shaped form is typical of the duodenum during the perinatal period. Starting from the 7th month of the intrauterine development the tissue layers of the duodenal wall are clearly differentiated. Two periods of an accelerated development (months 5 and 8-10) and a period of a slowed down development (months 6-7) are characteristic of the duodenum throughout the perinatal period
