Peritoneum Flashcards
What are some examples of organs with retroperiteonal viscera?
aorta, pancreas, duodenum, ascending and descending colon, kidneys, and IVC
What separates the abdominal muscles from the parietal peritoneum?
the transversalis fascia
the spleen is protected by which ribs?
9-11 (inferior left costal margin)
What ligaments is the greater momentum formed by?
gastrocolic, gastrolienal, and gastrophrenic
What ligaments is the lesser momentum formed by?
hepatogastric and hepatoduodenal
Where does the hepatogastric ligament run?
connects liver and lesser stomach
What umbilical fold do the inferior epigastric arteries run with?
lateral
What two ligaments attach the spleen to other structures?
gastrolienic and ilenorenal/splenorenal (to left kidney)
Does the spleen sit above or below the transverse mesocolon?
sits on it (above) on the left-most margin
The part of the colon where the transverse transitions to ascending and descending is what what?
right and left (respectively) colic flexures
What attaches the jejunum and ileum to the posterior abdominal wall?
mesentery proper
What is the anterior border of the omental bursa?
posterior surface of the stomach, gastrocolic ligament, and lesser omentum
What is the inferior border of the omental bursa?
transverse colon and transverse mesocolon
What is the superior border of the omental bursa?
left lobe of the liver and posterior lamina of the left coronary ligament
What umbilical fold does the obliterated umbilical artery run with?
medial
What umbilical fold does the obliterated arches run with?
median
The mental nurse communicates with the greater peritoneal sac via what?
epiploic foramen of Winslow
Is the greater momentum composed of perietal or visceral peritoneum?
visceral
T or F. mesenteries and ligaments in the abdomen form from parietal peritoneum reflections
F. they are from visceral peritoneum
Do retroperitoneal organs have visceral peritoneum?
No. just parietal
Where does the gastrocolic ligament run from?
lower stomach to transverse colon
What is attached inferiorly to the cecum?
appendix
What parts of the colon are intraperiteonal?
transverse (connects tranverse to pancreas) and sigmoid
What are the two parts of the periteonal cavity?
greater and lesser peritoneal sacs
When is the greater peritoneal sac formed?
developmental rotation of the foregut
The lesser peritoneal sac is aka?
omental bursa
What are the borders of the epiploic foreamen?
inferior- frist part of the duodenum
superior- the liver (caudate lobe)
anterior- IVC
posterior- hepatic portal vein in the hepatoduodenal ligament of the lesser omentum
What are the two mesogastric structures?
falciform ligament and lesser omentum
Gut rotation of the duodenum, jejunum, ileum and colon occurs around an axis formed by?
superior mesenteric artery
What lose their dorsal mesenteries during gut rotation 1?
ascending/descending colon, doudenum
What lose their dorsal mesenteries during gut rotation 2?
spleen
he right paracolic gutter has at its inferior end the vermiform appendix and at its superior end the?
hepatorenal recess (aka Morison’s pouch)
Being a low point in the peritoneal cavity of the supine patient, it is where excess intraperitoneal fluid (such as blood) collects
Midgut and hindgut structures have only have which mesentery?
dorsal. Some of these dorsal mesentaries are lost during fetal development in a process called gut rotation.
Do foregut structures have a ventral mesentery?
Yes
The remainder of the spell mesentery (the part not lost) is called the?
splenicorenal ligament
Remember that the splenic mesentery is derived from dorsal mesogastrium.
Just superficial to the parietal peritoenum is what?
transversalis fascia
