Flashcards in Lecture 15 - Peritoneal Cavity Deck (33):
1

The parietal peritoneum lines the _____nerve supply (___pain)

visceral peritoneum shares ____nerve supply (___pain)

The parietal peritoneum lines the somatic nerve supply (sharp pain)

visceral peritoneum shares visceral nerve supply (dull pain)

2

The major vessels are situated on the posterior wall on the vertebral coloum

The tributaries of these vessels transmit through the ______

mesentery

3

Alternating sections of intro and retro periteneaul give both..

motility and stability

4

Appendicitis - the initial pain is referring to the _____due to stretching of the visceral layer - when it inflames so much and stretches the parietal layer pain is very...

Appendicitis - the initial pain is referring to the umbilicus due to stretching of the visceral layer - when it inflames so much and stretches the parietal layer, pain is very painful and localised

5

The introperitoneal viscera fill the cavity so that the visceral surfaces touch each other or with the parietal perioneum, what happens when there is peristalsis?

They rub and glide over each other because of the peritoneum = friction free movement

only a few mls of serous fluid

6

The deepest layer - against the posterior wall has what?

adrenals, kidneys and ureters (paired viscera) - the TRUE retroperitoneal organs

7

True or False

The paired viscera a suitatued posterior to the unpaired viscera

true

8

True or False


IN the abdomen al the of the paired viscera belong to the urogenital system and endocrine system

true

9

everything unpaired is derived from what?

Primitive gut tube

10

The developinjg tract is a centrally placed tube - what suspends it fromt he posterior abdo wall?

dorsal mesentery

ventral mesentery suspends it from ant. wall

11

True or False

Everything derived from the primitive gut has a mesntery during development - then some come back and become retroperitoneal

true

12

What are the secondary retroperitoneal organs?

duodenum, pancrease, ascending /descending colon and bile duct

13

Where is the omental bursa (lesser sac) located?

behind the stomach

14

Where does the omental bursa (lesser sac) communicate with the Greater sac

the free edge of the lesser omentum (via the epiploic foreamen

15

THE mesentery is large and fan shaped, where does it start, travel from

the DJ flexure. (superiorly

path goes obliquely across the post. wall, aorta, vertrbral coloumn, IVC

then ends at ileocecal junction - near the upper border of the kright sacro-iliac joint`

16

What is in the fat, between the two peritoneal layers of the mesentery?

arteries
veins
nerves
Lymphatics

17

What does the transverse mesocolon connect?

the transverse colon to the posterior wall

18

THe two layers of the transverse mesocolon leave the posterior wall across the anterior surface of the head and body of the ______ and passoutward to surround the transverse colon

THe two layers of the transverse mesocolon leave the posterior wall across the anterior surface of the head and body of the pancreas and passoutward to surround the transverse colon

19

The anterior layer of the transverse mesocolon is adhered to the...

posterior layer of the greater omentum

20

Describe the sigmoid mesocolon?

Invetedm v-shaped peritoneum fold that attaches the sigmoid colon to the posterior abdominal wall

21

The apex of the V is near..

the division of the left common iliac artery

22

The double folds of the stomach's mesentery don't go straight to the wall - they take a detour, what is it?

ONe side attaches to the lesser curvature = lesser omentum

one side to the greater curvature = greater omentum

23

Where does the lesser omentum attache to

visceral surface of the liver - the free margin transmits the portal triad

24

What are the divisions of the lesser omentum:

medial hepatogastric ligament - passes between the stomach and the liver

Lateral hepatduodenal ligament - passes between the duodenum and liver

25

The Lateral hepatoduodenal ends as a free margin and serves as the anterior border of the _____ _______

The Lateral hepatduodenal ends as a free margin and serves as the anterior border of the omental foreamen

26

What is in this free edge at the hepatoduodenal ligaments end

hepatic artery proper
bile duct
portal vein

Also the entry point into the lesser sac

27

Which vessels are between the layers of the lesser omentum near the lesser curvature of the stomach

Right and Left gastric vessels

28

Does the lesser omentum cover all of the liver?

no

leaves a bare spot which touches the diaphragm

29

Where does the greater omentum attach inferiorly?

the peritoneum on the superior surface of the transverse colon and anterior layer of the transverse mesocolon before arriving at the posterior wall

30

What is the gastrolic ligament?

part of the greater omentum that goes over the top of the transverse colon

31

The greater omenum extends around the stomach superiorly in the form of which two ligaments?

gastrosplenic ligemant

gastrophrenic ligamant

32

The gastrosplenic lig. is a double fold that comes off the ______ and covers the spleen

The gastrosplenic lig. is a double fold that comes off the stomach and covers the spleen

33

What is the left lateral limit to the omental bura (Lesser sac)?

Gastrosplenic ligament
