Flashcards in Peritoneum Deck (38):
1

Foregut

derivaties - esophagus, stomach, duodenum, liver, pancreas
arterial supply - celiac a, splenic a, L gastric a, common hepatic

2

Midgut

derivaties - duodenum, free small intestine, cecum & appendix, ascending colon, R transverse colon
arterial supply - superior mesenteric a, ileocolic, R colic, middle colic

3

Hindgut

derivaties - L transverse colon, descending colon, sigmoid colon, rectum, upper part of anal canal, part of urogenital system
arterial supply - inferior mesenteric a, L colic sigmoind branch, superior rectal

4

parietal peritoneum

lines body wall in abdomen and pelvis
has abundant pain fibers via nerves of body wall

5

visceral peritoneum

covers visera
lacks pain fibers

6

Intraperitoneal organs

stomach
sm intestine
spleen
liver
gallbladder
cecum w/ veriform appendix
large intestine (transverse and sigmoid colon)

7

Primary retroperitoneal organs

kidney
ureters
adrenals
gonads

8

Secondary retroperitoneal organs

duodenum
pancreas
ascending and descending colon

9

THE mesentery

attaches free small intestine to body wall
dorsal mesentery - dorsal aorta & 3 branches run through
ventral mesentery - mesogastrium, respiratory diaphragm to duodenum

10

Transverse mesocolon

mesentery of transverse colon fuses with posterior layer of greater omentum

11

Sigmoid mesocolon

mesentery of sigmoind colon holds to posterior body wall

12

Mesoappendix mesentery

mesentery of verioform appendix

13

Peritoneal ligaments

transmit nerves and vessels
lack CT seen in ligaments that connect bones

14

Lesser Omentum

stomach & duodenum to liver
develops from ventral mesentery

15

Hepatogastric ligament

stomach to liver

16

Hepatoduodenal ligament

liver to duodenum

17

Greater omentum

develops form dorsal mesentery

18

Gastrocolic ligament

stomach to transverse colon

19

Gastrophrenic ligament

stomach to diaphragm, continuous with phrenicoslenic ligament

20

Gastrosplenic ligament

stomach to spleen

21

Peritoneal ligaments associated with the liver

coronary ligaments
R and L triangular ligaments
Falciform ligament (ligamentum teres hepatis)

22

median umbilical fold

urachus
midline from bladder

23

medial umbilical folds

medial umbilical ligaments

25

supravesical fossa

b/w median and medial umbilical folds
site for supravesical hernias

26

medial inguinal fossa

b/w the medial and lateral umbilical folds
site for direct inguinal hernias
also called inguninal triangle

27

lateral inguinal fossa

lateral to the lateral umbilical folds
site for indirect inguinal hernias

28

Greater sac of peritoneal cavity

most of the potential space within the abdomen

29

Supramesocolic region

superior and anterior to the liver and stomach
inculdes hepatorenal & subphrenic spaces & fossae of the anterior wall

30

Inframesocolic region

inferior and posterior part of the greater sac
R and L paracolic gutters are lateral to the ascending and descending colon
upper and lower parts of divided by THE mesentery into R and L infracolic spaces

potential space between the 2 layers of the gastrocolic ligament

34

Splenic recess

recesses of the lesser sac
posterior to and left of the stomach

35

Epiploic foramen
