Morphology and Morphometry of Ileum of the Newborn

Abstract

The main functions of the ileum testify to the perfection of its morphofunctional indicators. This study aimed to study the anatomical, histotopographic, and morphometric features of the lateral intestinal wall of newborn who died of traumatic brain injury at birth. The length of the ileum was 118.6 ± 12.5 ml in boys, shorter in girls - 104.3 ± 8.5 ml, the average number of peyer's patches was 9.4 ± 0.8. It was found that the epithelium covering the mucous membrane is single-layered, in some places multi-layered, their nuclei are disordered, the special plate is rich in histiogenic and lymphoid cells, which are differentiated to varying degrees. It was observed that the number of peyer's patches in the submucosal layer is relatively small, the lymphoid follicles in them completely occupy the submucosal layer and the special plate, the reticular and lymphocyte cells in them are sparse. While the wall thickness averaged 26,385 ± 342 μm, almost half of it corresponded to the mucous membrane, the suckers and crypts in it, and the rest to the submucosal, muscular, and serous membranes.
