Corpus: thick-walled, glandular section. Its walls have
secretory glands that produce digestive enzymes and mucus.
Digestion begins in the corpus. The pyloric sphincter controls the
movement of food from the corpus to the intestines (specifically,
the duodenum).
Diagram of the rat's
stomach. Adapted from Moore 2000
The forestomach and the corpus are separated by a low fold of tissue
called the limiting ridge
At the
esophagus, the course of the limiting ridge bends into a U-shape and
almost surrounds the esophageal opening
The esophagus is closed off from
the stomach by the gastroesophageal barrier, which consists of
the crural sling, the lower esophageal sphincter, and
the several centimeters of intraabdominal esophagus that lie between
them
Humans also have
a crural sling and an esophageal sphincter, but ours are placed right
on top of one another
Your presentation was very clear and you appeared very knowlegable about your article and topic! I also enjoyed your enthusiasm for the paper, and thought that the topic was interesting :)
