1

What is the peritoneum

A thin, serous membrane that covers all the organs and lines the abdominal cavity

2

What are the two layers of the peritoneum and where are they

The visceral peritoneum covers the abdominal viscera and organs
The parietal peritoneum lines the abdominal cavity

3

How would you describe and organ if it is completely surrounded in peritoneum

intraperitoneal

4

What are retorperitoneal organs

they only have peritoneum on their anterior surface

5

What organs and viscera are intraperitoneal (6)

Liver
Gall Bladder
Spleen
Stomach
Small intestine (most of)
Large intestine (some of)

6

What organs and viscera are retroperitoneal

S uprarenal glands
A orta & IVC
D uodenum (most of)
P ancreas (most of)
U reters
C olon
K idneys
O esophagus
R ectum

7

What is the mesentery

It's an organ that attaches the intestines to the abdominal wall and it allows nerves to communicate between the viscera and the abdominal wall
It is double layered

8

What is an omentum

The connections between viscera and other viscera

9

What are ligaments with regards to the peritoneum

These are between viscera and other viscera or viscera and the abdominal wall

10

Where is the lesser omentum between

The liver and stomach/duodenum

11

What ligaments are in the lesser omentum

Hepatogastric ligament and heptatoduodenal ligament

12

What structures are found within the hepatoduodenal ligament

The bile duct, hepatic vein and hepatic artery

13

Where is the greater omentum between

The stomach down to the transverse colon

14

How many layers does the greater omentum contain?

4

15

Where is the phrenicolic ligament between

The colon and diaphragm

16

Where is the lienorenal ligament between

The spleen and kidney

17

What are mesentery reflections

Reflections of two layers of visceral peritoneal lying on top of each other and connect to the abdominal wall

18

What do the lesser and greater sac communicate and pass fluid through

The omental foramen

19

Where can the omental foramen be found (what ligament is it behind)

The hepatogastric ligament

20

What three layers can be found within the greater sac

The supracolic, infracolic and pelvic areas

21

What are recesses in the abdomen

Small places that fluid can congregate

22

What recesses can be found in the infracolic region of the greater sac and what is their function

The paracolic gutters (either side of the left intestine)
Any fluid that accumulates in the infracolic region can settle in these gutters

23

What recess can be found in the pelvis in males

The vesicorectal pouch

24

What recesses can be found in the pelvis in female

Vesicouterine and rectouterine pouches

25

What is a problem if infectious fluid builds up within one peritoneal reflection

It may spread across the whole peritoneum as the spaces are consistent with one another

26

What can cause a build up of infectious fluid in peritoneal reflections and cavities?

Bacterial contamination during abdominal surgery
Rupture of the gut as a result fo infection/inflammation
When an ulcer in the stomach or duodenum perforates through the wall of an organ

27

What is the disadvantage of the paracolic gutters being linked with other recesses

They are able to spread infectious fluid or cancerous cells throughout the peritoneal organs

28

What is the role of the transversus abdominis muscle

It contains transverse fibres that support the viscera and rotates and flexes the trunk

29

What does the quadratus lumborum muscle do

Stavilises the 12th rib

30

What do the muscles psoas major/minor/iliacus do

They work with the hip flexor
