What kind of organ is the stomach?
distensible
What is the function of the stomach?
primarily digestive rather than absorptive, stores and mixes food with gastric secretion converting it to chyme
What are the parts of the stomach?
cardia
fundus
body
pyloric part
Where is the cardia of the stomach?
where esophagus joins stomach
Where is the fundus of the stomach?
above cardia
Where is the body of the stomach?
between fundus and pyloric part
Where is the pyloric part of the stomach?
most distal portion, adjacent to duodenum
What are the curvatures of the stomach?
greater and lesser curvature
What are the two notches of the stomach?
cardial and angular incisure
Where is the cardial notch?
between esophagus and fundus
Where is the angular incisure?
between body and pyloric part
What are the two openings of the stomach?
cardial and pyloric orifice
Where is the cardial orifice?
between esophagus and stomach
Where is the pyloric orifice?
between stomach and duodenum
What are the three parts of the pyloric part?
pyloric antrum, canal, and pylorus
What is the pyloric antrum?
wide proximal part
What is the pyloric canal?
narrow distal part
What is the pylorus?
distal termination of the pyloric part which contains the pyloric orifice and pyloric sphincter
What are Gastric folds (rugae)?
longitudinal folds of mucous membrane located in cavity of stomach to increase surface area
What is the blood supply of the stomach?
branches of the celiac trunk
What is the innervation of the stomach?
celiac plexus which originate from the sympathetic greater splanchnic nerves (T5-T9) and parasympathetic vagus nerve
Celiac trunk is the first _______ branch from the abdominal aorta
unpaired

common hepatic artery
What are the branches of the left gastric artery?
esophageal and gastric branches
What are the branches of the splenic artery?
pancreatic branches
short gastric arteries
left gastro-omental

anastomoses with the right gastric artery
Where does the splenic artery go?
spleen
What does the common hepatic artery turn into after giving off the gastroduodenal artery?
hepatic artery proper
Where does the pancreatic branches go?
pancreas
Where does the short gastric arteries go to?

What are the three branches of the gastroduodenal artery?
supraduodenal artery
right gastro-omental artery
superior pancreaticoduodenal artery
Where does the supraduodenal artery go?
superior aspect of duodenum
Where does the right gastro-omental artery go?
anastomoses with left gastro-omental artery
What are the branches of the hepatic artery proper
right gastric artery
right hepatic artery
left hepatic artery
Where does the right gastric artery go?
anastomoses with left gastric artery
Where does the right hepatic artery go?
right lobe of liver
What is the branch of the right hepatic artery?
cystic artery
Where does the cystic artery go?
gall bladder
Where does the left hepatic artery go?
left lobe of liver
What is the variation with the left and right hepatic artery?
middle hepatic artery can form off the middle of the two
