EX2 The Peritoneum and Upper Abdomen Flashcards
This is a thin, translucent, serous membrane where vessels tend to travel between the layers
peritoneum
What is the peritoneal sac
all visceral and parietal peritoneal membranes
What is the peritoneal cavity
a potential space within the peritoneal sac
contains serous fluid
allows organs to move freely
True or False
The peritoneal cavity may become filled with fluid
True; it can fill with fluid (ascites) and can cause disease and/or injury/infection
This attaches to the greater curvature of stomach and transverse colon; it drapes over the small intestine
greater omentum
The greater omentum serves to do what
it can wall off infections and inflammation site; an form adhesions
This ligament is the largest portion of the greater omentum and consist of 2 double layers –> 4 layers total
gastrocolic ligament
This attaches to the lesser curvature of the stomach and the duodenum and connect to the liver
lesser omentum
What are the two ligaments associated with the lesser omentum
hepatogastric ligament (liver to stomach) hepatodueodenal ligament (lifer to deodenum)
This ligament contains the portal triad
Hepatoduodenal ligament
it contains the hepatic artery, portal vein, and bile duct
This anchors most of the small intestine to posterior abdomen wall; running diagonally from duodenojejunal junction to ileocecal junction
mesentery proper
This fibromuscular ligament descends from the right crus of diaphragm crossing over the left crus and holds the duodenum in place (preventing sagging)
suspensory ligament of Treitz
This anchors portions of the colon to the posterior abdominal wall
mesocolon
True or False
The ascending and descending colon have no mesentery; they are anchored directly to the posterior wall
True
The transverse and sigmoid colons are anchored by what type of mesocolon
transverse colon –> transverse mesocolon
sigmoid colon –> sigmoid mesocolon
True or False
The rectum is fully covered with peritoneum
False; it is only partially covered
This divides the liver into right and left lobes; anchors the liver to the diaphragm and anterior body wall
falciform ligament
This is an inferior extension of the falciform ligament of which contains the obliterated umbilical vein
round ligament
This is a reflection of peritoneum around the bare area of the liver; attaches the liver to the inferior surface of the diaphragm
coronary ligament
What are the single layered peritoneal folds
median umbilical fold
medial umbilical folds (2)
lateral umbilical folds (2)
