1

Artery for the foregut

celiac trunk

2

Branches of Celiac trunk

Splenic, L gastric, Common hepatic

3

Artery for the midgut

superior mesenteric

4

Branches of Superior mesenteric a.

Ileocolic, R colic, Middle colic

5

7

Foregut supplies......

Esophagus, stomach, live, gallbladder, pancreas, upper duodenum, spleen (?)

8

Midgut supplies....

lower duodenum, jejunum, ileum, cecum, appendix, ascending colon, proximal 2/3 of transverse colon

9

Hindgut supplies...

distal 1/3 of the transverse colon, descending colon, sigmoid colon, rectum, and upper anal canal

10

Function of parietal layer of peritoneum

has pain fibers, lines body wall

11

Function of visceral layer of peritoneum

lacks pain fibers, covers viscera, autonomic innervation, can be sensed as referred pain

12

Referred pain is in reference to what layer of the peritoneum?

visceral

13

Definition of a mesentary

2 layers of peritoneum

14

Nerve supply to peritoneum supplies.....

pain and vasomotor fibers which can cause guarding from sharp stabbing pain when touched

15

T/F Visceral peritoneum is sensitive to touch, heat, cold, laceration

False, it is insensitive

16

What is visceral peritoneum sensitive to?

stretching and chemical irritation

17

What is the difference between intraperitoneal organs and retroperitoneal organs?

Intraperitoneal are suspended by a mesentary from the body wall and are surrounded by visceral pericardium
Retroperitoneal are deep to parietal peritoneum and covered by parietal peritoneum on ONE side

18

Primarily retroperitoneal vs Secondarily retroperitoneal

primary- never had a mesentary
secondary- had a mesentary but lost it at some point

19

What are the primary retroperitoneal organs?

kidney, ureters, adrenals, gonads, aorta and inferior vena cava

20

What are the secondarily retroperitoneal organs?

Duodenum, pancreas, ascending and descending colon, rectum

21

What are the intraperitoneal organs?

stomach, small intestine (J and I), spleen, liver, gallbladder, cecum + veriform appendix, large intestine (transverse and sigmoid)

22

What is THE Mesentery?

attaches the free small intestine to the posterior body wall, jejunum and ileum

23

What is the only function of a ventral mesentery?

extends from respiratory diaphragm to the duodenum

24

What is the mesentery for the transverse colon?

transverse mesocolon

25

What is the mesentery for the sigmoid colon?

sigmoid mesocolon

26

What is the mesentery for the vermiform appendix?

mesoappendix

27

2 periotneal ligaments

1. gastrosplenic
2. splenorenal

28

1. greater omentum
2. lesser omentum

29

Where does the greater omentum attach?

30

Where is the lesser omentum derived from?

31

2 subdivisions of the lesser omentum?

1. hepatogastric (liver, stomach)
2. hepatoduodenal (liver, duodenum)

32

What ligament contains the portal triad?

hepatoduodenal

33

What are the 3 components of the portal triad?

proper hepatic artery, hepatic portal vein, common bile duct
