Peritoneum & Upper Abdomen Viscera Flashcards
what is the thin serous membrane lining the inner abdominal wall
parietal peritoneum
what is the thin serous membrane lining the organs
visceral peritoneum
where does vasculature in reference to the peritoneum travel through
b/w the parietal and visceral peritoneal layers
what is the difference b/w the peritoneal sac and peritoneal cavity
sac is the term used to describe the ALL of the parietal and visceral membranes whereas cavity is the potential space w/in the sac where organs can move
what is the term used when the peritoneal cavity is overfilled w/fluid (pooling of fluids)
marked ascites and umbilical herniation
what is the potential space directly posterior to the stomach
omental bursa
what is the name of the anchoring ligament b/w stomach and spleen ?
gastrosplenic ligament
what is the name of the anchoring ligament b/w the spleen and kidney
splenorenal ligament
what is the greater omentum and where does it attach to
apron of fatty tissue draping over anterior surface of small int. like an apron
-attaches to greater curvature of stomach superiorly and transverse colon inferiorly
where is the lesser omentum and what does it attach to ?
sup. /medial to stomach
- attaches to lesser curvature of stomach and duodenum, and liver
what are the 2 portions of the lesser omentum that connects the stomach and duodenum to the liver
Hepatogastric ligament
Hepatoduodenal ligament
in what membrane can the portal triad be found and what passes through it ?
in the hepatoduodenal ligament of the lesser omentum
-hepatic a, portal v, common bile duct
what is the purpose of the mesentery proper
anchors most of small intestine to posterior abdominal wall
what is the suspensory ligament of Treitz and what does it function in
anchors the duodenum to posterior abdominal wall
-prevents sagging of dudenojejunal junction
what is the purpose of the mesocolon
its a mesentery that anchors parts of the colon to the posterior abdominal wall
what parts of the colon have NO mesentery
Ascending and Descending colon
what divides the liver into right and left lobes
falciform ligament
what is the purpose of the falciform ligament and what can be found at the inferior part of this ligament
anchors liver to anterior body wall and diaphragm
-round ligament of liver inferiorly
Where can coronary ligaments be found and what are their function
upper posterior bare area of the liver
-attatch liver to inferior diaphragm
what is the difference in peritoneal pouches in a standing/healthy patient vs. recumbent patients
potential spaces in standing patients BUT become actual spaces if constantly laying down
what are the 2 peritoneal pouches in a recumbent patient
hepatorenal pouch and rectovesical pouch
where would you find a rectovesicle pouch
b/w the rectum and bladder in men
where would you find a rectouterine pouch
b/w rectum and uterus in women
the Pouch of Morrison is also called ?
Hepatorenal pouch
what is the function of the liver
detoxifies chemical products and produce bile
function of the gall bladder
stores bile and emulsify fats
function of the pancreas
produce enzymes for digestion
function of the spleen
produce lymphocytes and filter blood
explain the flow of bile after it is produced in the liver
R and L hepatic ducts to
- -common hepatic duct which joins with the cystic duct to
- —–common bile duct to duodenum
what does the common bile duct join with before it empties into the major duodenal papilla
main pancreatic duct
what drain into the major duodenal papilla and what drains into the minor duodenal papilla
main pancreatic duct into major
accesory pancreatic duct into minor (2 cm. superior)eft
the spleen contacts the diaprhagm at what level
ribs 9-11
what is the hilum of the spleen
area on visceral surface where all vasculature enters the spleen
what are the 3 main branches of the celiac trunk
- common hepatic a.
- Left Gastric a.
- splenic a.
what organs does the celiac trunk supply
esophagus, stomach, liver, spleen, pancreas, gall bladder
the common hepatic a. has 2 terminal branches, what are they ?
- proper hepatic
- gastroduodenal
what does the proper hepatic a. bifurcate into
R and L hepatic aa.
what does the gastroduodenal a. divide into
- Superior pancreaticoduodenal a.
- Right gastroepiploic a.
where would you find the right gastroepiploic a. ?
on the greater curvature of the stomach
what does the splenic a. supply and what does it bifurcate into
spleen and pancreas
- short splenic aa
- Left gastroepiploic
what aretery is known for having multiple variations
hepatic aa.
what does the cystic a. supply ?
gallbladder and cystic duct
