visceral peritoneum shares ____nerve supply (___pain)

Answer 1

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

visceral peritoneum shares visceral nerve supply (dull pain)

Question 2

The tributaries of these vessels transmit through the ______

Answer 2

mesentery

Question 3

Alternating sections of intro and retro periteneaul give both..

Answer 3

motility and stability

Question 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…

Answer 4

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

Question 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?

Answer 5

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

only a few mls of serous fluid

Question 6

The deepest layer - against the posterior wall has what?

Answer 6

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

Question 7

True or False

The paired viscera a suitatued posterior to the unpaired viscera

Answer 7

true

Question 8

True or False

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

Answer 8

true

Question 9

everything unpaired is derived from what?

Answer 9

Primitive gut tube

Question 10

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

Answer 10

dorsal mesentery

ventral mesentery suspends it from ant. wall

Question 11

True or False

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

Answer 11

true

Question 12

What are the secondary retroperitoneal organs?

Answer 12

duodenum, pancrease, ascending /descending colon and bile duct

Question 13

Where is the omental bursa (lesser sac) located?

Answer 13

behind the stomach

Question 14

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

Answer 14

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

Question 15

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

Answer 15

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`

Question 16

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

Answer 16

arteries
veins
nerves
Lymphatics

Question 17

What does the transverse mesocolon connect?

Answer 17

the transverse colon to the posterior wall

Question 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

Answer 18

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

Question 19

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

Answer 19

posterior layer of the greater omentum

Question 20

Describe the sigmoid mesocolon?

Answer 20

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

Question 21

The apex of the V is near..

Answer 21

the division of the left common iliac artery

Question 22

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

Answer 22

ONe side attaches to the lesser curvature = lesser omentum

one side to the greater curvature = greater omentum

Question 23

Where does the lesser omentum attache to

Answer 23

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

Question 24

What are the divisions of the lesser omentum:

Answer 24

medial hepatogastric ligament - passes between the stomach and the liver

Lateral hepatduodenal ligament - passes between the duodenum and liver

Question 25

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

Answer 25

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

Question 26

What is in this free edge at the hepatoduodenal ligaments end

Answer 26

hepatic artery proper
bile duct
portal vein

Also the entry point into the lesser sac

Question 27

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

Answer 27

Right and Left gastric vessels

Question 28

Does the lesser omentum cover all of the liver?

Answer 28

no

leaves a bare spot which touches the diaphragm

Question 29

Where does the greater omentum attach inferiorly?

Answer 29

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

Question 30

What is the gastrolic ligament?

Answer 30

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