Flashcards in GI Viscera I Deck (16):
1

Name the unpaired branches of the abdominal aorta

Celiac trunk, Superior Mesenteric Artery, Inferior Mesenteric Artery, Middle Sacral artery (behind bifurcation of abd aorta)

2

Name the paired branches of the abdominal aorta

Inferior phrenic, Renal, Gonadal (testicular/ovarian), Common Iliac, Lumbar

3

List the arterial branches to the stomach

Left gastric, short gastric, left gastro-omental, right gastric, gastroduodenal, right gastro-omental

4

Where do the left and right gastric veins drain to?

The portal vein

5

The portal vein arises from what two veins?

The splenic vein and superior mesenteric vein

6

Where do the short gastric veins and left gastro-omental vein drain to?

The splenic vein

7

Where does the right gastro-omental vein drain to?

The superior mesenteric vein

8

Where does the prepyloric vein drain to?

The right gastric vein

9

Lymphatic drainage of abdominal viscera

Gastric and gastro-omental nodes to celiac nodes

10

Parasympathetic innervation to GI Viscera

Anterior/posterior vagal trunks

11

Sympathetic innervation to the stomach

Greater thoracic splanchnic nerve (T6-T9)

12

What is the advantage conferred by the retroperitoneal positioning of the distal three parts of the duodenum?

It secures the area around the common bile duct and major hepatic duct (enter 2nd part), which helps prevent these vessels from becoming kinked or twisted

13

Arterial supply to the duodenum

Celiac and SMA, Gastroduodenal, Anterior/posterior superior Pancreaticoduodenal arteries, Anterior/posterior inferior pancreaticoduodenal arteries (from SMA)

14

Where do veins draining the duodenum drain to and generally how do they get there?

The portal vein, either directly or indirectly via the splenic and SMV

15

Lymphatic drainage of the anterior vessels of the duodenum

Pancreaticoduodenal nodes and pyloric nodes

16

Lymphatic drainage of the posterior vessels of the duodenum

Superior mesenteric nodes
