Flashcards in Liver and Aorta Deck (41):
1

What part of the stomach does the lesser omentum attach to?

the body of the stomach (specifically the lesser curvature)

2

What part of the stomach sits directly under the left aspect of the diaphragm?

fundus

3

What part of the stomach directly communicates with the esophagus?

cardia

4

Review the following structures and understand their positioning in the stomach

Greater Curvature
Lesser Curvature
Cardia
Cardiac Notch Fundus
Body
Angular Notch
Pyloric Antrum
Pyloric Canal (Pylorus)
Pyloric Sphincter

5

The round ligament of the liver is the remnant of what pre-natal structure?

umbilical vein

6

The round ligament of the liver is aka?

ligamentum teres

7

What ligament contains the round ligament of the liver?

falciform ligament. At the superior aspect of the liver, the falciform ligament splits into left and right coronary ligaments which continue onto the superior surface of the liver

8

The coronary ligament attaches the liver to what?

diaphragm

9

Is the bare area of the liver found on the left or right lobe?

right

10

The transpyloric plane goes through which parts of the stomach?

pyloric canal and sphincter, and the body of the stomach. NOT the cardia or fundus

11

T or F. The spleen can be found mostly between the 9th and 11th ribs, medial to the midaxillary line

F. It can be found between the 9th and 11th ribs lateral to the medullary line

12

What part of the colon does the spleen sit on?

left colic flexure (aka the the splenic flexure)

13

What three facets make up the visceral surface of the spleen?

gastric, colic, and renal

14

Just lateral to the spleen is what recess?

costodiaphragmatic

15

What did the falciform ligament form from?

the ventral mesogastrium

16

What divides the liver into left and right lobes?

falciform ligament

17

The lower free margin of the falciform ligament contains what?

ligamentum teres

18

Does a normal liver extend inferior to the costal margin?

No. The lower margin of the liver is at the inferior costal margin

19

The fundus of the gall bladder sits at the level of what surface anatomy structure?

transpyloric plane (L1-L2)

20

Is the fossa for the ligament venosum medial or lateral to the IVC?

medial

21

What structures does the the porta hepatis of the liver contain?

the structures of the portal triad

22

What does the portal triad consist of?

the portal vein, which brings blood to the liver, the (proper) hepatic artery, which is bringing oxygenated blood to the liver, and the hepatic duct, which is the route of liver secretions (bile) to the gall bladder and duodenum.

23

What structure sits superior to the gallbladder in the liver?

IVC

24

The quadrate lobe of the liver sits between which structures of the H of the liver?

gallbladder and ligamentum teres

25

What drains blood from the liver? To what?

the right and left hepatic veins to the IVC

26

The falciform ligament splits to become what?

the left and right coronary ligaments

27

T or F. The inferior coronary ligaments on each side become the R and L triangular ligaments

F. The SUPERIOR coronary ligaments on each side become the R and L triangular ligaments

28

The gap between the superior and inferior parts of the right coronary ligament is called what?

the hepatic bare area

29

What is the only part of the liver not covered by visceral peritoneum?

the hepatic bare area

30

What is the clinical significance of the hepatic bare area?

It is important clinically because here lymphatic emissaries (vessels) pass unhindered between abdominal cavity and thorax. This provides a route for the spread of cancer from liver to lungs or from lungs to liver.

31

The junction of the right and left hepatic ducts forms what?

Common hepatic duct

32

The junction of the Common hepatic duct and the cystic duct forms what?

Common bile duct

33

just as it is entering the duodenum, the common bile duct is joined by what?

the pancreatic duct.

34

What happens to the common bile duct in between meals?

It becomes constricted and bile flows from the liver to be stored in the gall bladder. Local hormonal circuits are stimulated by the arrival of fats in the stomach which leads to the constriction of the common hepatic duct and expulsion of bile fluid from the gall bladder into the common bile duct into the duodenum.

35

Where does the celiac trunk branch from the abdominal aorta?

L1

36

What does the celiac trunk branch into?

left gastric artery, splenic artery, and common hepatic artery.

37

What are the main branches of the splenic artery?

1) short gastric artery
2) left gastroepiploic artery (to greater curvature)

38

What are the main branches of the left gastric artery?

1) branch to lower 1/3 of esophagus
2) continuation of the left gastric to the lesser curvature

39

What are the branches of the common hepatic artery?

1) gastroduodenal artery
2) continuation as the proper hepatic artery

40

What are the branches of the gastroduodenal artery?

1) anterior super pancreaticodoudenal artery
2) right gastricepiploic artery

41

What are the branches of the proper hepatic artery?

1) right gastric artery
