1

What are the arteries found in the midline vascular plane?

Celiac trunk
Superior and inferior mesenteric arteries
They are single arteries that come off the aorta at the midline.

2

What are the arteries found in the lateral paired vascular plane?

Renal artery
gonadal artery
suprarenal artery
They come off on either side of the aorta.

3

Where does the inferior suprarenal artery come off?

It comes off of the renal artery.

4

What artery supplies the diaphragm bilaterally, and where does it come from?

Inferior phrenic, comes off the aorta below the diaphragm, then travels superiorly to supply it.

5

Where does the superior suprarenal artery come from?

The inferior phrenic artery.

6

Where does the middle suprarenal artery come from?

Direct off the aorta.

7

What supplies the foregut?

Celiac trunk.

8

What supplies the midgut?

Superior mesenteric artery.

9

What supplies the hindgut?

Inferior mesenteric artery.

10

What lies in the foregut?

Inferior oesophagus, entire stomach, pancreas, and proximal duodenum until the major papilla.

11

What lies in the midgut?

Distal duodenum, post major papilla, jejunum, and ilium, caecum and appendix, ascending colon, most of the transverse colon, up to the splenic flexure.

12

What lies in the hindgut?

Splenic flexure and onward to the anal canal.

13

Where on the aorta does the celiac trunk branch off?

Just below the aortic hiatus.

14

Where does the left gastric artery supply, and where does it branch off of?

It is one of 3 branches of the celiac trunk, and goes to the lesser curvature, distal oesophagus. It is the shortest branch of the celiac trunk.

15

Where does the splenic artery supply, and where does it branch off of?

It is one of 3 branches of the celiac trunk, and goes to the spleen, travelling along the posterior face of the pancreas, supplying it. Goes to the gastrosplenic ligament, and supplies the spleen, then goes to the greater curvature, and gives off the left gastro-omental artery, which anastamoses with the right one. Gives off short gastric arteries superiorly. Longest and biggest branch of the celiac trunk.

16

Where does the common hepatic artery supply, and where does it branch off of?

It is one of 3 branches of the celiac trunk. Divides into 2 branches. One is the proper hepatic artery, which travels along the free edge of the lesser omentum, and enters the porta hepatis, and splits into left/right hepatic arteries.
The second branch of the common hepatic artery is the gastroduodenal artery, which gives off the right gastro-omental artery, as well as branches to the pancreas head, proximal duodenum, called pancreatic/duodenal branches.

17

Where does the right gastric artery come from, and where does it supply?

It comes off the proper hepatic artery, sometimes the common hepatic artery. It supplies the lesser curvature, and anastamoses with the left gastric artery.

18

What level does the celiac trunk come off at?

Proximal end of L1.

19

What level does the superior mesenteric artery come off at?

Distal end of L1.

20

Which artery do the pancreatic and duodenal arteries anastamose with?

Superior mesenteric artery.

21

What does the ileocaelal artery supply?

Caecum and appendix.

22

What supplies the appendix, and where does it come from?

Appendicular artery, which is the ileocaecal artery after it enters the mesoappendix.

23

What supplies the ascending colon?

Right colic artery.

24

What does the middle colic artery supply?

Transverse colon.

25

What are arcades, and which arteries have them?

They are honeycomb-like arteries close to the main artery, jejunal and ileal. They give off vasa recta, which are tall and column-like.

26

What are vasa recta?

They are tall column-like arteries that come off of arcades in jejunal and ileal arteries.

27

Where are arcades more dense? What about vasa recta?

Arcades are denser in the ileum, and vasa recta are smaller.
In the jejunum, vasa recta are longer and more pronounced, with fewer arcades.

28

What does the middle colic artery anastamose with?

Inferior mesenteric artery.

29

What level does the inferior mesenteric artery come off at?

L3.

30

Which side of thr aorta does the inferior mesenteric artery come off at?

More on the left side of the abdominal aorta.
