The stomach, part of the gastrointestinal tract, is a digestive organ located between the esophagus and the duodenum.
It has a 'J' shape, and features a lesser and greater curvature. The anterior and posterior surfaces are smoothly rounded with a peritoneal covering.
The greater curvature forms the long, convex, lateral border of the stomach. Arising at the cardiac orifice, it arches backwards and passes inferiorly to the left. It curves to the right as it continues medially to reach the pyloric antrum (opening to the pylorus).
What else can I help you with?
What is the bulge of the greater curvature of the stomach superior to the esophageal junction?
The fundus is the bulge of the greater curvature of the stomach superior to the esophageal junction.
Has a convex lateral surface called greater curvature and a concave medial surface called lesser curvature?
The stomach has a greater and lesser curvature. The greater curvature is the more lateral of the two.
Extends as a double fold from the greater curvature of the stomach?
Greater Omentum
The greater omentum arises from what part of the stomach?
The greater omentum arises from the greater curvature of the stomach. It is a large apron-like structure made of fatty tissue that hangs down over the intestines.
What are the attachments of the greater omentum?
The attachments of the greater omentum are: # The Dorsal Abdominal Wall # The Greater Curvature of the Stomach
Two layered serous membrane attached to the greater curvature of the stomach?
The greater omentum
Location and purpose of the greater and lesser omentum?
The greater omentum is located in the stomach. It is like an apron that extends from the greater curvature of the stomach to the transverse colon. Its purpose is for fat deposition, immune contribution, and infection and wound isolation. The lesser omentum, on the other hand, extends from the liver to the lesser curvature of the stomach. There is no known function of the lesser omentum.
Apron like structure which hangs form the greater curvature of the stomach and covers the anterior surface of the small intestine?
Greater Omentum
What is the function of the greater curvature?
Curvatures of the stomach:Lesser Curvature forms the right border of stomach, which extends from cardiac orifice to the pylorus. The lesser omentum is attached to lesser curvature and the liver. The lesser omentum forms the anterior boundary of the omental foramen and contains hepatic artery, portal vein and bile duct within its lower border.Greater Curvature extends from left of cardiac orifice, over dome of fundus, and along left border of stomach to the pylorus.The gastrosplenic ligament attaches to the upper part of the greater curvature and the greater omentum attaches to its lower part.
What structure defines the boundary between the stomach and esophagus?
There is no anatomical sphincter present at junction between stomach and esophagus. The angle formed by greater curvature of stomach demarcates the two organs.
What are the functions of the greater and lesser curvatures?
The greater and lesser curvatures are the two main curved surfaces of the stomach. The greater curvature serves as an attachment point for the greater omentum and provides a larger surface area for the stomach, facilitating the storage and mixing of food. The lesser curvature, on the other hand, connects to the liver via the lesser omentum and plays a role in the stomach's blood supply and movement during digestion. Together, they help in the mechanical and chemical processing of food.
Why carcinoma of stomach is common along the greater curvature?
Carcinoma of the stomach is commonly found along the greater curvature due to several factors, including the higher concentration of gastric acid and bile exposure in that area, which can contribute to mucosal damage and carcinogenesis. Additionally, the greater curvature is often more exposed to dietary carcinogens and has a different blood supply, which may influence tumor development. Furthermore, chronic conditions like gastritis, often prevalent in this area, can increase the risk of malignancy.
