Histomorphological and histochemical study of the cecum in moorhen, Gallinula chloropus, in Iraq

The goal of the current investigation is to understand the cecum s histological and histochemical composition in moorhens (Gallinulla chloropus). This study involved 10 birds that were used for the histological examinations of the ceca, which also included ceca determination. Hematoxylin and Eosin, Periodic Acid Schiff, and Alcian blue-(PH2.5) stain were used for staining the prepared histological slides. According to the findings, the cecum is a muscular tube made up of the four major tunics of the digestive tract: the tunica mucosa, submucosa, muscularis externa, and serosa. In the proximal portion of the ceca, the mucosa was created by the villi, and in the middle, it altered into folds or mounds that resembled flat mucosa. Simple columnar cells with a brush border and goblet cells lined the cecal mucosa. This epithelium expanded to line the Lieberkühn crypts in the folds and bases of the villi, which were situated between the villi and that which filled the lamina propria.
