Flashcards in Anatomy III (Peritoneum) Deck (27):
What is a mesentery?
umbrella term for double fold of peritoneum
2 functions of mesentery?
1. transmit nerves and vessels to intraperitoneal structures
2. allow mobility within intraperitoneum
What nerves does parietal peritoneum share?
What nerves does visceral peritoneum share?
Describe pain of appendicitis as it progresses
As it gets more inflammed, it pushes on visceral peritoneum(dull pain) then parietal peritoneum = localized sharp pain
What's the good and bad about the large surface area of the peritoneal space?
Bad: tumour/infection can spread very easily
Good: can use for peritoneal dialysis for exchange of fluids
Name 3 paired viscera: where are they located peritoneal-wise?
retroperitoneal and on post abdo wall
in the fetus how are all the abdo organs suspended?
by dorsal and ventral messentries
What organs are secondarily retroperitoneal?
ascending, descending colon
what organs are intraperitoneal?
What are the three layers of peritoneal and are they paired or not?
1. retro paired
2. secondary retro: unpaired
3. intraperitoneal: unpaired
lesser sac travels behind or in front of stomach/liver?
does the lesser sac communicate at all with the greater sac?
yes, only via epiploic foramen of Winslow
"THE" mesentery holds what? what is it's path?
starts at D-J junction, goes obliquely downward across aorta, IVC, right ureter
What is the mesocolon? what does it connect?
mesentery connecting large intestine to post abdo wall
Trace the path of the transverse mesocolon.
from tail of pancrease over 2nd part of duodenum
Where is the sigmoid mesocolon?
over division of left colon and iliac artery
lesser omentum attaches from where to where?
first inch of duodenum and lesser curvature of stomach extends to visceral surface of liver
Your finger is in the epiploic foramen of Winslow, what is:
on your finger
on: triad: bile duct, hepatic artery, portal vein
above: liver quadrate
What happens once omentum hits liver?
splits, wraps around it to tope of liver, reflects on diaphragm and becomes parietal layer
What's on top of liver regarding peritoneum?
There is a gap/bare spot where it visceral reflects to become parietal
What is the path of the greater omentum?
from grater curvature of stomach and duodenum. Drapes the front of transverse colon/small intestine and back up behind the liver
Path of gastro-phrenic ligament?
fundus of stomach straight to diaphragm
path of gastreo-lienal ligament?
stomach to spleen to post abdo wall
Which two mesenteries attach to the same place on the post abdo wall?
how many layers is the greater omentum?
4 layers 2 layers of 2 usually stuck together
