Final answer:
The posterior border of the stomach is also known as the greater curvature. It's part of the stomach's structure, which includes four major regions and is held in place by the lesser and greater omenta.
Step-by-step explanation:
The other name for the posterior border of the stomach is the greater curvature. The stomach has four major regions: the cardia, fundus, body, and pylorus. The greater curvature is the convex lateral surface of the stomach, which extends from the end of the esophagus to the beginning of the small intestine. It is opposed by the concave medial border called the lesser curvature. The stomach is connected to surrounding structures by the peritoneal folds, known as omenta. The lesser omentum suspends the stomach from the liver and follows along the lesser curvature, while the greater omentum hangs down from the greater curvature to cover the intestines and attaches to the posterior abdominal wall. Structurally, the wall of the stomach is composed of several layers with specialized adaptations to accommodate the stomach's digestive functions. These include an extra inner oblique smooth muscle layer that aids in the vigorous churning and mechanical breakdown of food.
