| Abstract | ||
| The present study was conducted to determine the anatomical and histological structure of stomach in adult local rabbits 6-12 month (Oryctolagus cuniculus). This study was carried out on 16 adult local rabbits which were divided into two groups: the first group contained 8 adult rabbits (4 male and 4 female) used for anatomical study include study of blood supply. The second group included 8 rabbits (4 male and 4 female) used for histological study using two types of stains, the hematoxylin and eosin and the special stain (PAS). Anatomically the stomach in both sexes of adult local rabbits was supplied through the celiac artery and its three branches. Histologically, in both sexes, the wall of the stomach consists of four tunics (tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa). There was no significant difference in thickness of tunics between male and female. The stomach lined by a surface lining mucous cells appears as a tall simple columnar epithelium that extends through gastric pits, where the gastric glands are opened, three regions can be recognized in the mucosa of the stomach according to the types of glands that appear as branched, tubular, coiled, short glands in both cardiac and pyloric glands region, while the fundic glands in the fundic glands region appear as simple branched tubular long straight over most of their length parallel to each other and coiled or bent at the basal portion. The cardiac and pyloric glands noted mainly mucous secreting cells and few numbers of parietal cells while the glands fundic region consist of different types of cells but the two main cells are the parietal and chief cells. The number of glands in the three regions was not different significantly between the male and female. The surface lining cells, gastric pits in three regions of stomach, cardiac and pyloric glands gave a positive reaction with PAS while the fundic glands showed a negative reaction with PAS in both male and female rabbit stomach. | ||
