| There is no consensus about the precise definition of what the cardia is. Although this term is often utilized in the medical literature, it takes on a variety of meanings, depending on the context. For histologists and endoscopists, the cardia is a region of the stomach immediately below the gastroesophageal junction. However, the concepts of gastroesophageal junction used by histologists and endoscopists are not the same as used by anatomists. This junction is histologically defined as the abrupt transition from the nonkeratinized stratified squamous epithelium of the esophagus to simple columnar epithelium and corresponds to the endoscopically defined Z-line. Nevertheless, this epithelial change does not occur exactly in the anatomical transition... |

| Foregut in D. hominis (Linnaeus Jr., 1781) as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the... |
