C6: Peritoneum and Retroperitoneum Flashcards
whats the peritoneal membrane composed of?
what the membrane contain?
connective tissue
-fat, blood vessels, lymphatics, nerves
whats the function of the peritoneal membrane?
- anchor organs
- creates ligaments and fold
- allow movement of organs
- reduce friction
during fetal development how does the peritoneal membrane change?
-its pushed anteriorly due to the movement of organs from the posteior abdo wall into the abdo cavity
what surface of retroperitoneal organs are in contact with the peritoneal membrane?
anterior surface (these organs dont migrate from the posterior abdo wall in utero)
what are ligaments
what do they contain
double fold or peritoneum that connect one organ to another
- blood vessels, lymphatics, nerves… which they connect to organs
which surface of the liver does the falciform ligament travel over?
what does this ligament connect?
the anterior, superior surfaces
-connects the umbilicus to the liver
which 2 ligaments form the lesser omentum
hepatoduodenal ligament and hepatogastric ligament
which ligament conducts the portal triad?
hepatoduodenal ligament
which ligaments are the corners of the bare area
triangular
another term for the splenorenal ligament
lienorenal
what are the posterior, left and right boundaries of morisons pouch
posteriorly:
the upper pole of the R kidney and diaphragm
left:
epiploic foramen of Winslow
right:
R lobe of liver and diaphragm
what are the 2 areas of the left sub hepatic space
anterior and posterior
the lesser sac sits in which potential space in the abdo
subhepatic spce
which other potential space communicates with the right sub hepatic space?
the posterior subphrenic space
another name for the lesser sac
omental bursa
whats the relationship of the greater sac to the lesser sac
- anterior superiorly
- posterior inferiorly
which sub compartments make up the supramesocolic compartment
subphrenic
subhepatic
which sub compartments make up the inframesocolic compartments
paracolic gutters
pelvic reflections
how is the inframesocolic compartment divided into L and R
by the root of the mesentery
how are the L and R inframesocolic compartments further divided
divided into medial and lateral by the ascending and descending colon
when is the mesentery seen on US?
with ascites
the retroperitoneum is anterior to which fascia
transversalis fascia (lines abdominal muscles
what are the superior and inferior boundaries for the retroperitoneum
diaphragm and pelvis brim
which other spaces does the anterior pararenal space communicate with
posterior pararenal space and the pelvis
what is the properitoneal space
potential space b/w the peritoneum and transversals fascia
study note package too. didn’t include all info here
.
The subphrenic space is divided into which smaller portions
Anterior and posterior
Which ligament runs through the falciform ligament
Lig teres… lig teres joins the LPV at the porta hepatis
Do the greater and lesser sac communicate
Yes at the epiploic foramen
Which part of the inframesocolic compartment doesn’t communicate with the pelvic cavity
R medial… blocked by messntary
Which ligament prevents the L lateral gutter from communicating with the L supramesocolic area
Phrenicolic ligament
How does the parietal peritoneum appear on US
What is the appearance called
Thin smooth echogenic line deep to the abdo wall muscles
Called the peritoneal line
Does the anterior parade all space have a midline communication
What about posterior
Yes
Posterior does not due to great vessels
Does the post perirenal space communicate with the pelvis
Yes
Which space in the retroperitoneum communicates with the properitoneal space
Post pararenal space
