Parts of the stomach

•

 

1 Fundus – the cranial portion under the diaphragm

   

•

 

1.1 Cardial notch (incisura cardialis) – a notch between the fundus and cardia

•

 

2 Body of stomach (corpus gastricum) – the largest part of the stomach

   

•

 

2.1 Cardia / cardial part (cardia / pars cardica) 

       – an area around the opening of the oesophagus

   

•

 

2.2 Cardial orifice (ostium cardiacum) – the opening of 

        the oesophagus into the stomach (at the level of T11)

        2.3 Gastric canal (canalis gastricus) 

       – a cavity within the body of the stomach

 

 

3 Pyloric part (pars pylorica)

      – a horizontal or slightly ascending part 

    of the stomach between the body and duodenum

   

•

 

3.1 Pyloric antrum (antrum pyloricum)

              – is located between the gastric

        and pyloric canals at the level of

        the angular notch 

   

•

 

3.2 Pyloric canal (canalis pyloricus)

       – a 2–3 cm long part heading

        towards the pylorus

   

•

 

3.3 Pylorus – the transition between

        the stomach and duodenum

   

•

 

3.4 Pyloric orifice (ostium pyloricum) – a closable

        outlet of the stomach into the duodenum

Arterial supply: 

coeliac trunk

Anastomosis along the lesser curvature: 

•

 

1 Left gastric artery (from the coeliac trunk) 

•

 

2 Right gastric artery (usually from the hepatic artery proper)

Anastomosis along the greater curvature: 

•

 

3 Left gastro-omental (gastro-epiploic) artery (from the splenic artery)

•

 

4 Right gastro-omental

Other branches:

•

 

5 Short gastric arteries

  6 Pyloric artery (from

Vein drainage:

portal vein

 – an important portocaval

  – the ventral surface of the pylorus is drained by the prepyloric vein (either via the right gastric vein or directly to the portal vein)
