GI Flashcards
what is the blood supply for the lesser curvature of the stomach?
left + right gastric branch of the hepatic artery
what is the blood supply of the greater curvature of the stomach?
short gastric arteries
left and right gastro-omental arteries
which ligament does the lesser curvature of the stomach give attachment to?
hepatogastric ligament
name the four sections of the stomach
fundus, body, pylorus, cardia
what level is the cardia?
T11
what does the pylorus connect to?
duodenum
Where is the angular notch?
where does the Inferior Oesophageal Sphincter pass through and at what level?
Oesphageal Hiatus - T10
what is the pyloric sphincter made of?
smooth muscle
Where does the greater omentum hang from and join to?
From the greater curvature and folds up to join to the transverse colon
Why does the greater omentum contribute largely towards gastrointestinal immunity?
contains lots of lymph nodes
Where does the lesser omentum originate from and join to?
Lesser curvature and joins to the liver
Via what does the greater and lesser sac communicate through?
Epiploic foraman
Where does the coeliac plexus arise from?

What does the splenic artery supply?
spleen
What are the three main branches of the abdominal aortus?
Left gastric, Splenic and Common hepatic
What does the splenic artery branch into and what do those branches supply?
body + tail of pancreas via pancreatic branches
fundus via short gastrics
greater curvature of stomach via left gastric-omentum
Which ligament is the splenic artery contained within?
splenorenal ligament
Describe the general route the splenic branch takes towards the spleen
posterior of stomach, across superior border of pancreas
Why is the splenic branch easily identifiable compared to the other branches?
Has a tortuous appearance
What does the Left gastric artery supply?
Stomach + oesophagus
What does the left gastric artery anastomose with?
Right gastric artery
What are the two main branches of the common hepatic artery?
Proper hepatic & gastroduodenal
What does the proper hepatic ascend through?
