I bought the Nikon 50mm 1.8G vs the Nikon DX 35mm 1.8G (which falls around $200 New) as my first prime lens because Nikon 50mm 1.8G was affordable entry level prime lens and knowing that i can use the same lens when i buy a full frame camera.
What is MÃ©nÃ©trierâs disease? MÃ©nÃ©trierâs disease causes the ridges along the inside of the stomach wallâcalled rugaeâto enlarge, forming giant folds in the stomach lining. The rugae enlarge because of an overgrowth of mucous cells in the stomach wall. In a normal stomach, mucous cells in the rugae release protein-containing mucus.
If the lining of the stomach is examined with a hand lens, one can see that it is covered with numerous small holes. These are the openings of gastric pits which extend into the mucosa as straight and branched tubules, forming gastric glands. Types of Secretory Epithelial Cells.1  Mucous cells: secrete an alkaline mucus that protects the epithelium against shear stress and acid. 2  Parietal cells: secrete hydrochloric acid! 3  Chief cells: secrete pepsin, a proteolytic enzyme. 4  G cells: secrete the hormone gastrin.here are differences in the distribution of these cell types among regions of the stomach-for example, parietal cells are abundant in the glands of the body, but virtually absent in pyloric glands.
