Lecture 15 - Peritoneal Cavity Flashcards
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)
The major vessels are situated on the posterior wall on the vertebral coloum
The tributaries of these vessels transmit through the ______
mesentery
Alternating sections of intro and retro periteneaul give both..
motility and stability
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
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
The deepest layer - against the posterior wall has what?
adrenals, kidneys and ureters (paired viscera) - the TRUE retroperitoneal organs
True or False
The paired viscera a suitatued posterior to the unpaired viscera
true
True or False
IN the abdomen al the of the paired viscera belong to the urogenital system and endocrine system
true
everything unpaired is derived from what?
Primitive gut tube
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
True or False
Everything derived from the primitive gut has a mesntery during development - then some come back and become retroperitoneal
true
What are the secondary retroperitoneal organs?
duodenum, pancrease, ascending /descending colon and bile duct
Where is the omental bursa (lesser sac) located?
behind the stomach
Where does the omental bursa (lesser sac) communicate with the Greater sac
the free edge of the lesser omentum (via the epiploic foreamen
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`
What is in the fat, between the two peritoneal layers of the mesentery?
arteries
veins
nerves
Lymphatics
What does the transverse mesocolon connect?
the transverse colon to the posterior wall
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
The anterior layer of the transverse mesocolon is adhered to the…
posterior layer of the greater omentum
Describe the sigmoid mesocolon?
Invetedm v-shaped peritoneum fold that attaches the sigmoid colon to the posterior abdominal wall
The apex of the V is near..
the division of the left common iliac artery
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
Where does the lesser omentum attache to
visceral surface of the liver - the free margin transmits the portal triad
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
