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.
