FAYETTEVILLE, Ark. -- Guessing about the contents of a cow's stomach is a thing of the past for University of Arkansas researchers - all they have to do is reach in and take a sample. The university's Animal Science Department has surgically implanted 4-inch-wide tubes, called cannulas, in the sides of 12 cows. The cannulas allow the scientists to get a real-time look at a bovine's stomach contents in a study of the effect of grazing on nutrient run off into river watersheds. On a recent...

Many of them had narrow, pointed teeth, which were more suited to tearing off plants rather than chewing them. But how did they then grind their food? Until recently many researchers have assumed that they were helped by stones which they swallowed. In their muscular stomach these then acted as a kind of 'gastric mill'. But this assumption does not seem to...

NEW YORK (Reuters Health) - Researchers believe a kind of stomach pacemaker could be a viable treatment for obesity.

The Gastric Chief Cell (peptic cell or gastric zymogenic cell) is a cell found in the stomach that releases pepsinogen, gastric lipase and Chymosin (an enzyme that clots milk). Pepsinogen is only released when the cell is stimulated by a number of factors, including cholinergic activity and increased acidity in the stomach. The gastric chief cell works in conjunction with the parietal cell, which releases gastric acid, converting pepsinogen into pepsin. The term “chief cell” is...
