STOMACH

STOMACH

1. Intraperitoneal hollow organ

2. Lies below left dome of diaphragm

3. Abdominal esophagus opens into stomach via cardial orifice

   • Into the CARDIA which is continous with FUNDUS of stomach
     • FUNDUS is separated from heart by the CENTRAL TENDON of DIAPHRAGM

4. Cardiac Notch=Junction between esophagus and fundus

5. Pylorus is infront of Inferior VC

   • Pylorus begins at angular inscicure which is on lesser curvature
     • Pylorus opens via Pyloric orifice
   • Arising from the lesser curvature is Hepatogastric ligament

6. Arising from greater curvature is the greater omentum (3 PARTS)

   • GASTROCOLIC LIGAMENT
     • STOMACH --> TRANSVERSE COLON
   • GASTROPHRENIC LIGAMENT
     • STOMACH---->DIAPHRAGM
   • GASTROSPLENIC LIGAMENT
     • STOMACH--->SPLEEN

7. ARTERIAL SUPPLY

   • LESSER CURVATURE
     • RIGHT GASTRIC
     • LEFT GASTRIC
       • LEFT GASTRIC forms anastomoses with right gastic artery at the cardia
   • GREATER CURVATURE
     • GASTROOMENTAL LEFT
       • BRANCH OF SPLENIC
     • GASTROOMENTAL RIGHT
       • BRANCH OF GASTRODUODENAL

8. VENOUS SUPPLY

   • Entire drainage---->HEPATIC PORTAL VEIN
   • Through the SPLENIC, LEFT GASTRIC, SUP MESENTERIC VEINS

9. NERVOUS SUPPLY

   • Sympathetic
     • CELIAC NERVE PLEXUS
   • Parasympathetic
     • BRANCHES OF VAGUS NERVE
     • Secretes gastric juice and HCL
     • Improves gastric motility

10. Body of the stomach makes up the greater part of the stomach.

    • Continuous with the PYLORIC PART
      • Divided into pyloric antrum and pyloric canal

11. LYMPHATICS

    • Gastric, Splenic, Pyloric, Gastroomental Nodes
