Flashcards in Peritoneal Cavity Deck (26):
1

What are the two layers of the peritoneum and which is inner and which is outer?

Parietal (outer) and Visceral (inner)

2

Where are the two layers of the peritoneum continuous?

At the mesentery

3

What kinds of things run through mesentery?

Arteries, veins, lymphatics, nerves

4

An otherwise healthy individual presenting in severe abdominal pain is likely to be what condition and what is the cause related to?

Acute abdomen. Related to the innervation of the peritoneum

5

What is the innervation of the parietal and visceral peritoneum respectively?

Parietal - Somatic innervation, Visceral - Autonomic innervation

6

What type of pain stimulus does the visceral peritoneum respond to?

Stretching

7

A patient has appendicitis first aggravating the visceral peritoneum, then eventually the parietal peritoneum. What type of pain will the patient feel first (during visceral aggravation) and what type later (during parietal aggravation)?

Diffuse pain in areas such as umbilicus during visceral, Severe localized pain over the appendix during parietal

8

Referred shoulder pain may result from aggravation of what abdominal organ and through what nerve is this transmitted?

The peritoneal surface of the diaphragm becoming inflammed or aggravated may be transmitted through the phrenic nerve (C3,4,5) and perceived as shoulder pain

9

In males and females respectively, is the peritoneal cavity completely closed?

Yes in males, no in females

10

What structure has openings into the peritoneal cavity?

The uterine tubes

11

Ascites

Excessive fluid in the peritoneum

12

What does the peritoneal cavity develop from?

The intraembryonic coelom

13

Three mesenteries

Mesentery of small intestine, Transverse mesocolon, Sigmoid mesocolon

14

What does it mean if an organ is secondarily retroperitoneal?

The organ had a mesentary (was intraperitoneal) but lost it

15

Three organs that are secondarily retroperitoneal

Duodenum, ascending colon, descending colon

16

What are the two peritoneal sacs, what is the alternate name for one of them, and what is the space between them?

Greater peritoneal sac, Lesser peritoneal sac (omental bursa). They are separated by omental foramen

17

What are the four borders of the omental foramen and which border is each?

IVC (posterior), Hepatoduodenal ligament (Anterior), Liver (superior), Duodenum (inferior)

18

What does the greater omentum do?

It is the policeman of the abdomen, responding to chemical signals and moving from one side to the other

19

What two structures does the falciform ligament run between?

Umbilicus and liver

20

What are the two parts of the lesser omentum and which is on which side?

Hepatogastric ligament (left part between liver and lesser curvature), Hepatoduodenal ligament (right side)

21

The three peritoneal folds

Lateral umbilical fold, medial umbilical fold, median umbilical fold

22

The supracolic compartment is above what structure?

The transverse mesocolon

23

What separates the right and left infracolic spaces?

The root of mesentery of the small intestine

24

Paracolic gutters

Allow communication between supracolic and infracolic regions

25

Give the spaces within which ascitic fluid, pus, and tumor cells might move between supracolic and infracolic spaces when erect and supine respectively

Paracolic gutters (erect) and Subphrenic recess (supine)

26

What is the most dependent region of the standing female pelvis and what does this mean?

The rectouterine pouch. It means fluid will gravitate here
