Q

What are the ligaments of the spleen and where do they go?

A

1) gastrolienal ligament (ventral)- to stomach

Q

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?

A

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

Q

Notes on artery branches off the gastroduodenal artery

A

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

Q

What enters the porta hepatis on the visceral side of the liver?

A

the proper hepatic artery, the common bile duct, and the hepatic portal vein (these enter through the hepatoduodenal ligament)

18
Q

What structure entering the porta hepatis is most dorsal?

A

the hepatic portal vein. The proper hepatic artery and the common bile duct are ventral

19
Q

What does the cystic artery do? Where does it come from?

A

supplies the gallbladder

comes from the right hepatic artery (off the proper hepatic artery)

20
Q

Is the origin of the hepatic portal vein superficial or deep to the neck of the pancreas?

A

deep

21
Q

The common hepatic duct arises from the junction of what?

A

the right and left hepatic ducts

22
Q

The junction of the cystic duct (from where?) and the common hepatic duct make what?

A

the common bile duct

cystic duct drains the gallbladder

23
Q

What does the common bile duct descend in?

A

the hepatoduodenal ligament to the 2nd part of the duodenum

24
Q

What part of the duodenum does the common bile duct enter into?

A

2nd (along with the main pancreatic duct?

25
Q

The quadrate lobe and most of the caudate lobe are supplied by what artery?

A

the left hepatic artery

26
Q

Is the beginning of the branches of the celiac trunk retroperitoneal?

A

Yes, they are retro until they enter a reflection of peritoneum to reach their respective viscera

27
Q

the celiac trunk might be seen behind which ligament?

A

hepatogastric ligament

28
Q

What is contained in the lienorenal ligament?

A

tail of pancreas and the splenic vessels (splenic artery)

29
Q

The left gastroepiploic artery supplies what?

A

the left aspect of the greater curvature of the stomach

30
Q

Where does the anastomose of the right and left gastroepiploic arteries occur?

A

as they course they enter the greater momentum (gastrocolic ligament) and anastomose and supply the greater curvature of the stomach

31
Q

At the stomach what the left gastric artery enter?

A

the lesser momentum (hepatogastric ligament) where it anastomoses with the right gastric artery, a branch of the proper hepatic artery

32
Q

As the left gastric artery enter the lesser momentum, what does it give off?

A

an esophageal branch to the distal end of the esophagus in the abdomen

33
Q

What are the two branches of the common hepatic artery?

A

proper hepatic and gastroduodenal

34
Q

What ligament can the proper hepatic artery be found in?

A

the hepatoduodenal ligament of the lesser momentum (it runs to the left of the common bile duct in the ligament)

35
Q

What does the proper hepatic branch into? Where?

A

right and left gastric arteries in the aorta hepatis

36
Q

What part of the duodenum does the gastroduodenal artery run posterior to?

A

the 1st

37
Q

What are the branches of gastroduodenal artery?

A

the anterior superior pancreaticoduodenal artery and the right gastroepiploic artery (which enter the greater omentum)

38
Q

Is the liver protected by the right costal margin?

A

yes it is deep to it

39
Q

What are the two surfaces of the liver?

A

the diaphragmatic (smooth and facing anteriorly and superiorly) and the visceral (contains hilum and attaches to lesser omentum)

40
Q

Does the falciform ligament extend below the umbilicus?

A

No

41
Q

What structures pass into the liver through the hepatoduodenal ligament?

A

the proper hepatic artery, the hepatic portal vein, and the common bile duct
