What does greater curvature mean?
Medical Definition of greater curvature : the boundary of the stomach that forms a long usually convex curve on the left from the opening for the esophagus to the opening into the duodenum — compare lesser curvature.
What is sulcus intermedius of stomach?
Anatomical Parts Directly opposite the incisura angularis of the lesser curvature the greater curvature presents a dilatation, which is the left extremity of the pyloric part; this dilatation is limited on the right by a slight groove, the sulcus intermedius, which is about 2.5 cm, from the duodenopyloric constriction.
What is the function of the greater curvature of the stomach?
The addition of an inner oblique smooth muscle layer gives the muscularis the ability to vigorously churn and mix food. The convex lateral surface of the stomach is called the greater curvature; the concave medial border is the lesser curvature.
What is the curvature of the stomach?
The curvatures of the stomach refer to the greater and lesser curvatures. The greater curvature of the stomach is four or five times as long as the lesser curvature….
| Curvatures of the stomach | |
|---|---|
| Artery | Greater: short gastric (upper part), left gastroepiploic (middle) Lesser: Right gastric artery and left gastric artery |
Where is the greater curvature of stomach?
The convex greater curvature of the stomach starts at the left of the cardia and runs from the fundus along the left border of the body of the stomach and the inferior border of the pylorus.
What does lesser curvature mean?
Medical Definition of lesser curvature : the boundary of the stomach that in humans forms a relatively short concave curve on the right from the opening for the esophagus to the opening into the duodenum — compare greater curvature.
Which side is the stomach curved?
Its characteristic shape is well known. The right side of the stomach is called the greater curvature and the left the lesser curvature. The most distal and narrow section of the stomach is termed the pylorus—as food is liquefied in the stomach it passes through the pyloric canal into the small intestine.
What organ lies behind the stomach?
Lying behind the stomach is the pancreas. A large double fold of visceral peritoneum called the greater omentum hangs down from the greater curvature of the stomach.
Why is the stomach curved?
What is the function of lesser curvature?
The lesser curvature gives attachment to the two layers of the hepatogastric ligament, and between these two layers are the left gastric artery and the right gastric branch of the hepatic artery.
