Topographic and Anatomical Features of the Liver in the Ante and Postnatal Ontogenesis

Abstract

The purpose of this work was to study the age anatomy of the liver (her gate, furrow, blood vessels), as well as its topography in Ante and postnatal ontogenesis in humans (in fruits, newborns, children of different age, teenagers, young men, adults and elderly people and senile age).  Periods of the most intense growth of weight and liver weight and volume are immediately before birth and 4 cm - 9 cm months of breast age.  The weight of the liver is maximized by 1- cm. The period of mature age (1644, 06 ± 75.90 g), the volume is in the youth of the age (1435.20 ± 8.56 cm3).

It is shown that the quadrangular shape of the antenatal liver changes in the postnatal period on triangular and in highly age-shaped.  A variety of forms of liver shares in fruits is replaced after birth with characteristic sustainable for each share form.  It has been established that the perimeter of the extra-breech field of the liver becomes the maximum in the youth of the age, the size of the corpuscular, crucible, and triangular ligaments - in adults, the size of the lig. hepatoduodenal - in the elderly.  Revealed age features of the distribution of types, sizes, and position of the gate of the liver.  It is shown that the type of gates (98%) is closed in fruit and newborns (98%) during childhood and adolescence, the open type of liver gate in adults (61%), in elderly and old age (80%).
