9. Peritoneal Cavity and Mesenteries Flashcards
Which embryological structure gives rise to the greater omentum?
The dorsal mesogastrium.
What arteries run within the greater omentum?
The posterior gastric arteries.
The short gastric arteries.
The left gastric omental artery.
The right gastric omental artery.
What is the lowest place in the abdominal cavity for fluid to collect?
In males, it is the rectovesicular space.
In females it is the rectouterine space.
From which mesentery do the hepatoduodenal and hepatogastric ligaments arise?
The ventral mesentery.
What arteries run within the hepatogastric ligament?
The right and left gastric arteries.
(Recall that the right gastric artery also runs within the hepatoduodenal ligament.)
Which ligament does the splenic artery run in?
The splenorenal ligament.
From which mesentery does the falciform ligament arise?
The ventral mesentery.
What ligaments make up the greater omentum?
The gastrosplenic ligament.
The gastrocolic ligament.
The gastrophrenic ligament.
What arteries run within the gastrosplenic ligament?
The short gastric arteries.
Part of the left gastric omental artery.
Where is the lesser omentum found?
In between the stomach and the liver.
What are the borders of the lesser sac?
Anterior: lesser omentum (hepatoduodenal ligament / hepatogastric ligament), stomach, gastrocolic ligament.
Posterior: pancreas, left kidney and suprarenal gland, aorta, inferior vena cava, splenic artery and vein.
Superior: diaphragm and liver.
Inferior: transverse mesocolon and 1st part of the duodenum.
Left: hilum of the spleen and gastrosplenic ligament.
Right: epiploic (omental) foramen.
What arteries are contained within the mesentery proper?
The jejunal and illeal arteries.
The superior mesenteric artery.
Where are the superior mesenteric vein and artery in relation to the pancreas?
Behind the head, and tucking through the hook of the uncinate process.
The splenorenal ligament and the gastrosplenic ligament are a part of which mesentery?
The dorsal mesentery.
What arteries run within the gastrophrenic ligament?
The posterior gastric arteries.
