| Abstract: The current investigation comprised histological study of fourth compartment (abomasums) of one humped camel’s stomach in adult animals, were included (5) specimens from adults were used. The histological study of fourth compartment (abomasums) of stomach revealed that it lined simple columnar epithelium, it was noted that the lamina propria composed of loose connective tissue. In the same direction, the results referred that there were three regions in the Lamina propria of fourth compartment, the cardiac region has cardiac glands, fundic region has fundic glands, in which gastric cells were found including mucous neck cells, chief cells, argentaffin cells & parietal cells which constitutes the vast majority of gastric cells. The third region was the pyloric region which contained pyloric glands. The result also showed that all the gastric glands besides the mucous neck cells gave a positive reaction with (PAS) reagent. The muscularis mucosae appeared more developed in the fourth compartment in which it consisted of an inner layer of circularly arranged muscle fibers, and an outer longitudinal layer. The submucosa was observed consisted of loose connective tissue with different types of blood vessels, fibroblasts & small lymphocyte. The smooth muscle fibers of muscularis externa consisted of an inner layer in which the muscle fibers are arranged circularly & an outer layer in which the fibers run longitudinally. Covering the muscle coat, there is the outermost serous layer which made up of loose connective tissue contained fibroblasts, collagenous & elastic fibers. | ||
