In the pyloric region appeared a group of the epithelial cells collected to form elevated mountain areas which, from the dorsal view, take the shape of volcanic crater due to the presence in the center of deep and wide gastric pits
. The gastric pits
were surrounded by layers of epithelial cells of different levels which gave it the appearance of volcanic crater (Fig.
The glandular epithelium was a simple columnar epithelium, with spherical or flat nuclei located in the base of the cell, which was more dwarf than gastric pit
. Meanwhile, nucleolus could be observed in the closely arranged nucleus.
: For the first time, gastric pits
begin to appear at the 8th week at the fundus and corpus regions of the stomach (34).
Observed in (a): evidence of disorganization of the columnar simple epithelium in the gastric pits
(enlarged detail, arrowhead) and gastric glands (arrows), congestion of the blood capillaries (enlarged detail, asterisk), and necrosis of the gastric mucosa cells (enlarged detail); in (b): preserved columnar simple epithelium in the gastric pits
(enlarged detail) and well- preserved gastric glands (arrow); in (c): nonpreserved gastric mucosa with exfoliation of the simple columnar epithelium (enlarged detail); in (d): gastric mucosa with slight focal exfoliations of the simple columnar epithelium and preserved gastric mucosa (asterisk); and in (e): preserved gastric mucosa and simple columnar epithelium (enlarged detail).
The gastric glands in between the gastric are branched tubular glands compactly arranged and characterized by various types of cells Pyloric part Epithelium has got lots It is made up of loose of stomach of gastric pits
lined by connective tissue columnar cells.
The mucous layer of the fundic region of the stomach presented short gastric pits
lined by a simple cylindrical epithelium consisting exclusively of mucus-secreting cells.
