HISTOMORPHOLOGICAL STUDIES ON THE ILEUM, CAECUM AND ASCENDING COLON IN MIXED BREED DOGS IN TRINIDAD
2020
Mohamed, Reda | Mazher, Khaled
The anatomical and histological features of the ileum, caecum and ascending colon were studied in six adult apparently healthy mixed breed dogs. The ileum communicated directly with the ascending colon via the ileocolic opening where the ascending colon begun. The caecum appeared as a distinct coiled outpouching from the proximal part of the ascending colon. The fine openings of the lymphoid nodules were seen in the mucosal surface of the caecum and first part of the ascending colon. The intestinal glands of the lamina propria and the lymphoid nodules of the submucosa of the ileum in the male dog were fewer and smaller than that of the female. The mucosa of the caecum and the first part of the ascending colon of the female dog was thinner with more goblet cells and larger lymphoid nodules than that of the male dog. The mucosa of the last part of the ascending colon showed less goblet cells with more lymphoreticular tissue in between the intestinal crypts. The lymphoid structures of the ileum, caecum and ascending colon were lack of cortex and medulla as well as germinal centers.
