Lab Guide- 52 to 54 Flashcards
Does the stomach ever pass the midline into the right side of the body?
Yes. at the transpyloric plane (L1-L2), where it is continuous with the 1st part of the duodenum
What indicates the transition from the body of the stomach to the pylorus?
the angular notch. Note that the cardia and funds of the stomach are both deep to the left costal margin
The lateral (diaphragmatic) surface of the spleen is protected by which ribs?
9-11
Where is the hilum of the spleen on the diaphragmatic surface?
It is on the visceral surface, not the diaphragmatic surface.
What are the ligaments of the spleen and where do they go?
1) gastrolienal ligament (ventral)- to stomach
2) lienorenal ligament (dorsal)- to left kidney (contains the tail of the pancreas and the distal splenic vessels)
What are the branches of the celiac trunk (the most superior unpaired branch of the aorta)? Are they retroperitoneal?
Where does the celiac trunk branch from the aorta?
left gastric artery, common hepatic artery, and splenic artery (the origin and initial courses of these branches are retroperitoneal until they enter a reflection of peritoneum to reach their respective viscera)
branches at level of L1 at the superior aspect of the pancreas at the midline
Which of the three branches of the celiac trunk is the largest?
splenic
Does the splenic artery run anterior or posterior to the body of the stomach?
posterior (it is often embedded in pancreatic tissue)
What part of the stomach does the short gastric artery supply?
fundus
Is the left gastric artery intraperitoneal or retroparitoneal?
retroperitoneal (so is the common hepatic)
What does the proper hepatic artery branch into?
the right and left hepatic arteries (and the right gastric artery)
What artery supplies the gallbladder? Where does it come from?
cystic artery from the right hepatic artery
What arteries supply the greater curvature of the stomach?
right and left gastroepiploic arteries (the anastomose happens within the greater omentum)
What does the anterior superior pancreaticoduodenal artery anastomose with?
the anterior inferior pancreaticoduodenal artery from the superior mesenteric artery
this anastomosis occurs deep to the neck of the pancreas
Notes on artery branches off the gastroduodenal artery
in addition to the anterior superior pancreaticoduodenal artery, the gastroduodenal artery also gives off a posterior superior pancreaticoduodenal artery which anastomoses with the posterior inferior pancreaticoduodenal artery from the superior mesenteric artery
Is the liver completely covered by visceral peritoneum?
No, the bare area is not
What enters the porta hepatis on the visceral side of the liver?
the proper hepatic artery, the common bile duct, and the hepatic portal vein (these enter through the hepatoduodenal ligament)
What structure entering the porta hepatis is most dorsal?
the hepatic portal vein. The proper hepatic artery and the common bile duct are ventral
What does the cystic artery do? Where does it come from?
supplies the gallbladder
comes from the right hepatic artery (off the proper hepatic artery)
Is the origin of the hepatic portal vein superficial or deep to the neck of the pancreas?
deep
The common hepatic duct arises from the junction of what?
the right and left hepatic ducts
The junction of the cystic duct (from where?) and the common hepatic duct make what?
the common bile duct
cystic duct drains the gallbladder
What does the common bile duct descend in?
the hepatoduodenal ligament to the 2nd part of the duodenum
What part of the duodenum does the common bile duct enter into?
2nd (along with the main pancreatic duct?
