Histological Studies on the Stomach of Albino Rat (Rattus norvegicus)

Abstract

The present study on albino rats revealed that the mucosa of glandular stomach was comprised of cardiac, fundic and pyloric regions based on the nature of glands. In the cardiac and pyloric region, the glands were branched tubular coiled and consisted almost entirely of mucous secreting cells along with a few chief cells. In the fundic region, the proper gastric (fundic) glands were simple tubular and longer than the cardiac glands. Four distinct cell types comprised the mucous, chief, parietal and endocrine cells. At the pyloric duodenal junction, muscle layers were thickened to form the pyloric sphincter.
