Q: The [...] peritoneum lies the [...].
A: parietal; abdominal cavity
Comment 2: BUT NOT THE ORGANS
green = parietal peritoneum

Q: What is a peritoneum?
A: A serous membrane that lines an organ or cavity

What is a mesentery? What does it contain?

What are 2 examples of a mesentery?

Q: The visceral peritoneum covering the [...] travels down the liver, becoming the [...].
A: liver; lesser omentum
Q: The lesser omentum covers the [...] and becomes the [...].
A: stomach; greater omentum
Q: The greater omentum covers the [...] and travels back, attaching to the [...].
A: transverse colon; posterior abdominal wall

Q: What are the 2 ligaments contained in the lesser omentum?
A: 1) Hepatogastric ligament
2) Hepatoduodenal ligament

Q: What is the location of the hepatogastric ligament? Does it contain vessels?
A: Liver--> lesser curvature of the stomach
Contains gastric vessels

Q: What is the location of the hepatoduodenal ligament? Does it contain vessels?
A: Liver-->proximal duodenum
Contains the PORTAL TRIAD (hepatic artery proper, portal vein, common bile duct)

Q: What is the Pringle maneuver? What is its purpose?
A: Pringle maneuver = clamp the hepatoduodenal artery = reduce bleeding (if present) from the hepatic artery proper & portal vein
The purpose of this is to ID the source of a bleed. If bleeding continues after the Pringle maneuver, the source of bleeding is NOT from the hepatic artery proper or portal vein, but must be from the retrohepatic vena cava or hepatic veins.

Q: What 2 ligaments are contained in the greater omentum?
A: 1) Gastrocolic ligament
2) Gastrosplenic ligament

What is the location of the gastrosplenic ligament? Does it contain any vessels?

Q: What is the location of the gastrocolic ligament? Does it contain any vessels?
A: NO VESSELS

Q: The [...] & [...] colon are retroperitoneal and thus [...] connect to the greater omentum.
A: ascending; descending; do NOT
Q: The [...] colon is NOT retroperitoneal and consequently [...] connect to the greater omentum.
A: transverse; does

What is the location of the splenorenal ligament? Does it contain vessels?

What ligament contains the gastric vessels? Is it located in an omentum?

What ligament contains the portal triad? Is it located in an omentum?

Q: What ligament contains the splenic artery & vein? Is it located in an omentum?
A: NOT IN OMENTUM

What ligament contains the branches of the splenic artery & vein? Is it in an omentum? List the names of the branches.

Q: The [...] ligament contains the splenic artery & vein, while the [...] artery contains the branches of these vessels.
A: splenorenal; gastrosplenic

Where is the falciform ligament located? Does it contain vessels?

Q: What contains the ligamentum teres?
A: Falciform ligament

What is the ligamentum teres? How is it created?

How does portal HTN affect the ligamentum teres?

What ligament contains the paraumbilical veins?

Where is the retroperitoneum?

Q: What structures are retroperitoneal?
A: "SAD PUCKER"
Suprarenal (adrenal) glands
Aortic/IVC + branches
Duodenum (2nd + 3rd parts)
Pancreas
Ureters
Colon (ascending + descending)
Kidneys
Esophagus
Rectum

Q: What are the symptoms of retroperitoneal structure injury?
A: Organ dysfunction + hemodynamic instability (due to compression of local structures = IVC + aorta)

Q: When a retroperitoneal organ is damaged, suspect [...] are damaged.
A: other retroperitoneal organs

Q: ID structures A-D.
A: A = liver
B = diaphragm
C = lesser omentum
D = falciform ligament

F = transverse mescolon
G = transverse colon
H = greater omentum

L = urinary bladder

Q: ID structures M-Q.
A: M = pancreas
N = duodenum
O = mesentery proper
P = sigmoid mescolon

Q: ID the greater omentum. What 3 ligaments does it contain?
A: F = greater omentum
1) gastrophrenic ligament
2) gastrosplenic ligament
3) gastrocolic ligament

Q: ID the ligament that is located from the greater curvature of the stomach to the transverse colon. What omentum contains it?
A: I = gastrocolic--greater omentum

Q: ID structure G.
A: G = gastrophrenic ligament

Q: ID the ligament that contains the BRANCHES of the splenic artery & vein.
A: H = gastrosplenic ligament (within greater omentum)

Q: ID the ligament that contains the paraumbilical veins.
A: A = falciform ligament

Q: ID the structure that contains the ligamentum teres.
A: A = falciform ligament

Q: What is another name for the ligamentum teres?
A: ROUND LIGAMENT!

Q: ID the round ligament. What structure is it contained in?
A: B = round ligament (aka ligamentum teres)
Contained in the falciform ligament (A)

Q: ID the lesser omentum. What do ligaments does it contain?
