Organs Supplied By Celiac Trunk

Front 1

First major branch of abdominal aorta

Back 1

celiac trunk aka celiac artery

Front 2

Three branches of celiac trunk

Back 2

L gastric artery; Common hepatic artery; splenic artery

Front 3

Where does the L gastric artery go?

Back 3

It <b>ascends</b> from the celiac trunk towards junction of esophagus and stomach (cardia). When it reaches this, it goes down along lesser curvature.

Branches of it also go to the esophagus.

Front 4

Where does the common hepatic artery go?

Back 4

First it extends to the right from the celiac trunk. It gives rise to several things - gastroduodenal artery, proper hepatic artery, and Right gastric artery.

Front 5

What do the proper hepatic artery, R gastric artery, and gastroduodenal artery branch off?

Back 5

Common hepatic artery (which itself branches from celiac trunk)

Front 6

What does the gastroduodenal artery become?

Back 6

It goes posterior to the duodenum, then
1) posterior superior pancreatico-duodenal artery (PSPuD)
2) Anterior superior pancreatico-duodenal artery (ASPuD)
3) Ends as right gastroepiploic artery (greater curvature of stomach)

Front 7

What arteries supply the lesser curvature of stomach?

Back 7

1) L gastric artery
2) R gastric artery (small branch of common hepatic artery)

Front 8

What arteries supply the greater curvature of stomach?

Back 8

1) R gastroepiploic artery (end of Gastroduodenal)
2) L gastroepiploic artery

Front 9

What does the proper hepatic artery branch to?

Back 9

R and L hepatic arteries

The cystic artery supplies the gall bladder and <b> usually</b> is a branch of the R hepatic a.

Front 10

What does the cystic artery supply?

Back 10

Gallbladder. It's usually a branch of the R hepatic a, which is a branch of the proper hepatic a, which is a branch of the common hepatic a, which is a branch of the celiac trunk.

Front 11

What are the three main ventral branches of aorta?

Back 11

1) Celiac trunk
2) Superior mesenteric a. (SMA)
3) Inferior mesenteric a. (IMA)

Front 12

Why is the splenic artery serpentine?

Back 12

The splenic a. is a branch of the celiac trunk that exits and goes left to supply the spleen. The stomach is bigger when full and pushes the spleen to the left, so the artery that supplies it must be able to length to still get to it.

Front 13

What are the branches of the splenic artery?

Back 13

1) L. gastroepiploic (anastomoses with R. gastroepiploic, itself the end of the gastroduodenal) to supply the greater curvature of the stomach.
2) Multiple pancreatic branches
3) Short gastric arteries

Front 14

Name of the sphincter that controls exit into duodenum from stomach

Back 14

Pyloric

Front 15

Groove along the inner surface of lesser curvature that liquids tend to follow

Back 15

Gastric canal

Front 16

What do the short gastric arteries (branches of splenic a.) supply?

Back 16

fundus and upper body of stomach

Front 17

What do the L and R gastric v drain into?

Back 17

Hepatic portal vein

Front 18

What veins drain the greater curvature?

Back 18

Gastro-omental veins

Front 19

What veins drain the lesser curvature?

Back 19

Gastric (coronary) veins

Front 20

Where do the lymphatics of the stomach drain?

Back 20

Nodes named after gastric vasculature (aka gastric, gastro-omental)

Ultimate destination is the celiac lymph nodes.

Front 21

What nerves slow stomach activity? Where do they come from?

Back 21

The sympathetic fibers slow gastric activity. They come from the greater splanchnic nerve. (Segments T6-T9)
Ganglia are in the celiac ganglia.

Front 22

What nerves enhance stomach activity?

Back 22

Parasympathetic (rest and digest).

Anterior and posterior vagal trunks. Postganglionic, have v short axons, located in walls of stomach.

Front 23

What is the name of the thing the esophagus passes thru to get to stomach?

Back 23

esophageal hiatus

Front 24

What is the name of the space anterior to liver?

Back 24

Subphrenic recess

Front 25

What separates liver into R and L main lobes?

Back 25

Falciform ligament

Front 26

What is the name of the space posterior to liver?

Back 26

Subhepatic recess and hepatorenal recess.

Front 27

What becomes the lowest space in the ab cavity lying down?

Back 27

Heptorenal recess. Also has a direct connection with lesser sac

Front 28

What Marks a division
between the
Quadrate and Left
lobes of the liver

Back 28

Ligamentum teres aka round ligament

Front 29

Opening in liver that allows hepatic portal vein and proper hepatic a in, and allows bile duct out

Back 29

Porta hepatis

Front 30

What is the lobe closest to the gallbladder?

Back 30

Quadrate

Front 31

What is a portal system?

Back 31

Connects two sets of capillaries

Front 32

What two capillary beds does the hepatic portal vein drain into?

Back 32

capillaries of the guy into the capillaries (sinusoids) of the liver.

Front 33

What is the exception to the food that gets "seen" by the liver?

Back 33

Fat

Front 34

What is another name for the hepatic capillary system, which contains the hepatocytes?

Back 34

Sinusoids

Front 35

After blood goes thru the sinusoids, where does it go?

Back 35

To the hepatic vein (NOT hepatic portal vein, it's already been there)

Front 36

What forms the hepatic portal vein?

Back 36

Splenic vein, superior and inferior mesentery veins

Front 37

What happens in portal hypertension?

Back 37

Results from restriction of hepatic portal blood flow, a common consequence of cirrhosis of liver.

When this occurs, alternate drainage must be found for the blood that can't make it thru the liver.

Front 38

What is porta-caval anastomosis?

Back 38

specific type of anastomosis that occurs between the veins of portal circulation and those of systemic circulation. The lower end of esophagus is one of the important sites for the port systemic anastomosis . In portal hypertension the anastomosis opens and forms venous dilatation called esophageal varices. Their rupture causes severe and dangerous haematesis

Front 39

4 areas of porta-caval anastomosis (name of clinical condition from problems with them)

Back 39

1) Esophagus (esophageal varices)
2) Anus (hemorrhoids)
3) Umbilicus (caput medusa)
4) Retroperitoneal veins

Front 40

What makes up the portal triad?

Back 40

1) Biliary duct
2) Hepatic portal vein
3) Proper hepatic a
