Card 1 of 25Question

What is the lesser curvature of the stomach?

The short, concave border of the stomach extending from the cardia toward the pylorus.

In This Section

1. What is the lesser curvature of the stomach?

The short, concave border of the stomach extending from the cardia toward the pylorus.

2. Which borders of the stomach are formed by the lesser and greater curvatures?

The lesser curvature forms the right and superior border, while the greater curvature forms the left and inferior border.

3. Which anatomical notch is located along the lesser curvature?

The angular incisure, also called the incisura angularis.

4. What does the angular incisure indicate anatomically?

The junction between the body and pyloric part of the stomach along the lesser curvature.

5. Which major peritoneal structure attaches along the lesser curvature?

The lesser omentum.

6. Which part of the lesser omentum directly connects the lesser curvature to the liver?

The hepatogastric ligament.

7. Which surface of the liver is connected to the lesser curvature through the lesser omentum?

The visceral surface of the liver.

8. Which two arteries form an anastomotic pathway along the lesser curvature?

The left gastric and right gastric arteries.

9. From which artery does the left gastric artery usually arise?

The celiac trunk.

10. From which artery does the right gastric artery most commonly arise?

The proper hepatic artery, although its origin is variable.

11. In which direction does the left gastric artery travel along the lesser curvature?

Inferiorly and rightward from the cardiac region toward the pyloric region.

12. In which direction does the right gastric artery travel along the lesser curvature?

Leftward from the pyloric region toward the left gastric artery.

13. Through which peritoneal structure do the gastric arteries travel along the lesser curvature?

Between the layers of the hepatogastric ligament.

14. Into which venous system does blood from the lesser curvature ultimately drain?

The hepatic portal venous system.

15. Where does the left gastric vein usually drain?

Into the hepatic portal vein.

16. Where does the right gastric vein usually drain?

Into the hepatic portal vein.

17. Which lymph nodes receive lymphatic drainage from the lesser curvature?

The right and left gastric lymph nodes along the gastric vessels.

18. Which major lymph node group ultimately receives much of the lymph from the lesser curvature?

The celiac lymph nodes.

19. Which nerves supply parasympathetic fibers along the lesser curvature?

Branches of the anterior and posterior vagal trunks.

20. What are the nerves of Latarjet?

Longitudinal gastric branches of the vagal trunks that travel along the lesser curvature.

21. What are the crow's foot branches of the gastric vagal nerves?

Terminal vagal branches supplying the distal stomach, particularly the pyloric antrum.

22. Which autonomic plexus provides sympathetic fibers to the lesser curvature?

The celiac plexus, through periarterial branches accompanying the gastric arteries.

23. What is the gastric canal along the lesser curvature?

A longitudinal mucosal pathway formed by gastric folds that may direct swallowed liquids toward the pylorus.

24. Why is the lesser curvature important during selective gastric vagotomy?

The gastric vagal branches run nearby and may be selectively divided to reduce acid secretion.

25. Which region of the lesser curvature is a recognized site of gastric peptic ulcers?

The area near the angular incisure, particularly at the junction of the body and antrum.
