- partly in left hypochondrium
- gatsro-oesophageal junction provides physiological sphincter through
increased muscles tone, supported by fibres
around right crus of diaphragm
- lesser curvature (superiorly)
- runs along with left and right gastric arteries
- greater curvature (inferiorly)
- runs along with left and right gastro-epiploic arteries
- fundus
- all stomach above level of cardiac orifice
- body
- pyloric antrum
- bottom end of stomach from angular notch
- pyloric sphincter
- allows food to pass out into duodenum in small boli
- 1cm to right of midline in transpyloric plane
- blood suppy
- 3 branches of coeliac artery
- left gastric anastomoses with right gastric (from gastroduodenal
artery)
- splenic artery gives off left gastro-epiploic
- hepatic artery gives off right gastro epiploic artery, superior
pancreatico duodenal artery, right gastric artery
- stomach may herniate through oesophageal hiatus of diaphragm (hiatus
hernia)

| Surface markings of stomach, pylorus |
|
| Abdominal oesophagus; gastro-oesophageal junction and ‘sphincter’
mechanism. |
|
| Stomach: fundus, body; pyloric region (antrum, canal,
sphincter); lesser curvature, greater curvature. |
|
| Greater omentum, lesser omentum; attachments to stomach;
lesser sac. |
|
| Hiatus hernia; pyloric stenosis. |
Gastric ulceration |
| Coeliac artery to stomach and proximal duodenum
(foregut): left and right gastric arteries; left and right gastroepiploic
arteries |
Short gastric branches of splenic artery; gastroduodenal,
pancreatico-duodenal arteries |
