Study Notes
Arterial Supply to the Stomach
- The main arterial supply to the stomach is from the celiac trunk.
- The left gastric artery is supplied by the celiac trunk.
- The right and left gastric arteries, along with the short gastric arteries, supply the stomach with blood.
Venous Drainage of the Stomach
- The right and left gastric veins drain into the portal vein.
Lymphatic Drainage of the Stomach
- Lymph is drained from the stomach into the celiac nodes, except for the fundus, which drains into the pancreaticosplenic nodes.
Innervation of the Stomach
- The vagus nerve supplies parasympathetic innervation to the stomach.
- Autonomic innervation to the stomach is provided by sympathetic and parasympathetic nerve fibers.
Gastric Ulcers
- A common cause of gastric ulcers is Helicobacter pylori infection.
- A potential complication of gastric ulcers is perforation, which can lead to peritonitis.
- A chronic ant perforated ulcer can invade the pancreas, leading to pancreatitis.
- A chronic post perforated ulcer involving the splenic artery can lead to bleeding.
Other Relevant Information
- The gastrosplenic ligament attaches from the upper part of the greater curvature of the stomach to the hilum of the spleen.
Test your knowledge on the anatomy of the gastric and gastroepiploic veins, including their connections and lymphatic drainage patterns. Also, explore the nerve supply to these structures. Perfect for medical students or anyone interested in human anatomy.
