The body of the stomach is related to what structures anteriorly and posteriorly?
Anteriorly: abdominal wall
Posteriorly: omental bursa
The visceral surface of the spleen has 3 facets. Name them.
Renal (posterior), Colic (inferior), and Gastric.
Which parts of the stomach are located in the transpyloric plane?
pyloric canal and sphincter
The SPLENORENAL ligament contains?
The tail of the pancreas and the splenic vessels.
At what vertebral level does the celiac trunk arise?
L1 - TRANSPYLORIC PLANE
Three main branches of the celiac trunk.
Splenic, Left Gastric, and Common Hepatic
What branches off the distal end of the Splenic Artery?
Short gastric branches to the fundus of the stomach, and the left gastroepiploic artery to the greater curvature of the stomach.
The Gastroepiploic arteries run in and supply what ligament?
Gastrocolic
The gastric arteries run through what ligament?
Hepatogastric (NOT HEPATODUODENAL)
The right gastric artery is a branch of the…..
Proper Hepatic Artery
Where does the common hepatic artery fork and what branches does it form?
Splits at the duodenum to form the proper hepatic artery and the gastroduodenal artery.
What is the pathway of the proper hepatic artery?
Runs through the hepatoduodenal ligament to the porta hepatis, where it splits into right and left hepatic arteries.
What is the one branch of the Right Hepatic Artery called?
Cystic artery (to the gallbladder)
What is the pathway of the gastroduodenal artery?
Runs posteriorly to the first part of the duodenum then terminates into the right gastroepiploic, supra duodenal and the anterior/ posterior superior pancreaticoduodenal arteries.
From what artery does the anterior inferior pancreaticoduodenal artery arise?
Superior Mesenteric Artery
What anastomosis does the pancreaticoduodenal arteries create?
An anastomosis between the celiac trunk and the SMA.
What is the largest gland in the body?
The liver
What quadrant is the liver located in?
Upper Right
Name the two surfaces of the liver.
Diaphragmatic and visceral
Where does the falciform ligament end?
Superior to the umbilicus
Name the 3 structures in the hepatoduodenal ligament.
Portal Vein, Hepatic artery, and Common bile duct.
Where are the hepatic veins located?
Hepatic veins empty directly into the IVC and can be seen in the fossa of the IVC
The H-shaped area of the liver contains what structures?
1-Ligamentum teres
2- Ligamentum venosum
3- Gallbladder
4-IVC

Caval/CAUDATE
What lobe of the liver is located in between the gallbladder and the ligamentum teres?
Quadrate lobe
What lobe of the liver is located between the IVC and the ligamentum venosum?
Caudate
The cystic duct joins with what to become the common bile duct?
Common hepatic duct (formed by fusion of R&L hepatic ducts)
