where lesser curvature abruptly angles to right, body of stomach ends, and antrum begins
where fundus forms with left margin of esophagus
angle of His
arterial blood supply to stomach
main arteries: L and R gastric along lesser curvature
L and R gastroepiploic arteries along greater curvature
also inferior phrenic and short gastric along proximal stomach
about what percentage of aberrant left hepatic originate from left gastric
largest artery to stomach
generally, maximal number of arteries that can be ligated, if arcades along greater and lesser curvatures are intact, for stomach to survive with enough blood flow
3 of 4 main arteries
venous drainage of stomach
L gastric (coronary) and R gastric veins drain into portal vein usually. L gastroepiploic drains into splenic vein. R gastroepiploic drains into SMV.
what happens to L and R vagus at GEJ?
L vagus becomes anterior, R becomes posterior (LARP)
Extrinsinc parasympathetic and sympathetic innervation of stomach
PS via vagus, S via celiac plexus
Where SNS supply to stomach originates from?
T5 to T10 (travels in splanchnic n to celiac ganglion)
vagus that gives off hepatic branch to liver and continues along lesser curvature as anterior n. of Latarjet?
nerve giving off branch to celiac plexus, and continuing posteriorly along lesser curvature
