Flashcards in Anatomy III (Peritoneum) Deck (27):
1

What is a mesentery?

umbrella term for double fold of peritoneum

2

2 functions of mesentery?

1. transmit nerves and vessels to intraperitoneal structures
2. allow mobility within intraperitoneum

3

What nerves does parietal peritoneum share?

somatic

4

What nerves does visceral peritoneum share?

autonomic

5

Describe pain of appendicitis as it progresses

As it gets more inflammed, it pushes on visceral peritoneum(dull pain) then parietal peritoneum = localized sharp pain

6

What's the good and bad about the large surface area of the peritoneal space?

Bad: tumour/infection can spread very easily
Good: can use for peritoneal dialysis for exchange of fluids

7

Name 3 paired viscera: where are they located peritoneal-wise?

kidneys
adrenals
ureters
retroperitoneal and on post abdo wall

8

in the fetus how are all the abdo organs suspended?

by dorsal and ventral messentries

9

What organs are secondarily retroperitoneal?

ascending, descending colon
bile duct
pancreas
duodenal

10

what organs are intraperitoneal?

stomach
jejunum/ileum
cecum/appendix
transverse colon
sigmoid colon

liver
gall bladder
spleen

11

What are the three layers of peritoneal and are they paired or not?

1. retro paired
2. secondary retro: unpaired
3. intraperitoneal: unpaired

12

lesser sac travels behind or in front of stomach/liver?

behind

13

does the lesser sac communicate at all with the greater sac?

yes, only via epiploic foramen of Winslow

14

"THE" mesentery holds what? what is it's path?

small intestine
starts at D-J junction, goes obliquely downward across aorta, IVC, right ureter

15

What is the mesocolon? what does it connect?

mesentery connecting large intestine to post abdo wall

16

Trace the path of the transverse mesocolon.

from tail of pancrease over 2nd part of duodenum

17

Where is the sigmoid mesocolon?

over division of left colon and iliac artery

18

lesser omentum attaches from where to where?

first inch of duodenum and lesser curvature of stomach extends to visceral surface of liver

19

Your finger is in the epiploic foramen of Winslow, what is:
on your finger
behind
beneath
above?

on: triad: bile duct, hepatic artery, portal vein
above: liver quadrate
behind: IVC
beneath: duodenum

20

What happens once omentum hits liver?

splits, wraps around it to tope of liver, reflects on diaphragm and becomes parietal layer

21

What's on top of liver regarding peritoneum?

There is a gap/bare spot where it visceral reflects to become parietal

22

What is the path of the greater omentum?

from grater curvature of stomach and duodenum. Drapes the front of transverse colon/small intestine and back up behind the liver

23

Path of gastro-phrenic ligament?

fundus of stomach straight to diaphragm

24

path of gastreo-lienal ligament?

stomach to spleen to post abdo wall

25

Which two mesenteries attach to the same place on the post abdo wall?

transverse mesocolon
greater omentum

26

how many layers is the greater omentum?

4 layers 2 layers of 2 usually stuck together

27

What is the purpose of the omental bursa of the lesser peritoneal sac?

allow frictionless expansion of stomach when needed
