| Summary: | Stomach macroscopical and microscopical investigations of ten adult male wild rabbits collected from AL-Najaf city markets recorded to gives a support for future researches and clinical applications as look upon the biology of the digestive system. After rabbit's preparation, the stomach recognized then the shape, position, dimensions and its relations with the other abdominal organs were records. The outer shape of the stomach is taken J- like shape. It lies in the cranial part of the abdominal cavity entirely within the rib cage, mostly to the left of the median plane. It consists of the visceral and parietal surfaces and greater and lesser curvatures. The mean length of the greater and lesser curvatures was (22.3±0.9 cm) and (4.64±0.9 cm) respectively. Stomach connected with spleen, pancreas, and colon by thin mesenteric folds. The internal surface of the stomach consists of two parts, glandular and non-glandular. The first part consists of three regions, the cardiac, fundus, and pyloric regions. The mean length of non-glandular and three glandular regions were (2.3 ± 0.38 cm), (2.28 ± 0.4 cm), (6.38 ± 0.23 cm), and (4.3 ± 0.29 cm) respectively. The non-glandular region covered by stratified squamous epithelium. The cardiac and fundus regions covered by simple columnar epithelium. The pyloric region covered by a low columnar to the cuboidal epithelium. Invaginations of the glandular epithelium to forms tubular branched and coiled glands. Smooth muscle of muscularis mucosa two layers, tunica submucosa was loose connective tissue, tunica muscularis showed bundles of smooth muscle fibers arrange into internal circular, and external longitudinal layers which facing externally with loose connective tissue of adventitia. |
