1. What is the peritoneum?
Ans: serous membrane lining the abdominal cavity
2. What are its 2 layers?
Ans: parietal lines body wall; visceral lines organs
3. Where can you find the visceral peritoneum?
Ans: Lining organs
4. What is the peritoneal cavity?
Ans: Potential space between parietal and visceral peritoneum
5. What are mesenteries?
Ans: Extensions of parietal or visceral peritoneum folded over.
6. What are its 2 functions?
Ans: Support and stabilize organs, holds organs to each other or to abd wall,
provide passageway for vessels & NN between layers, allow movement for
digestion.
7. What is the greater omentum?
Pretest - Stuvia US
,2
Ans: Hangs from stomach/duodenum to trans colon/post body wall
8. What is the lesser omentum?
Ans: From top of stomach (less curve) to liver; where celiac trunk AA lie
9. What are the 2 parts of the lesser omentum?
Ans: Gastrohepatic and hepatoduodenal lig (ligs here are more like
peritoneum)
10.What is the mesentery proper?
Ans: Mesentery of small intestine; attaches small intestine to post abd wall
11. What is the mesocolon?
Ans: Mesentery of colon (large intestine); anchors colon to posterior body
wall
12.What are the peritoneal ligaments?
Ans: Folds of peritoneum that connect organ w/ another or abd wall
13.What is the coronary ligament?
Ans: Visceral peritoneum that attaches liver to diaphragm
14.What is the falciform ligament?
Ans: Attaches liver to ant abd wall; divides R&L lobes of liver
Pretest - Stuvia US
,3
14-5. What is the ligamentum trees?
Ans: Round lig of liver (NB-adult) or umbilical V (fetus)
15.What is the gastrophrenic ligament?
Ans: Connects stomach to diaphragm
16.What is the gastrosplenic ligament?
Ans: Connects stomach to spleen; helps make greater omentum
17.What is the gastrocolic ligament?
Ans: the greater omentum
17-5. What is special about the bare area?
Ans: There is no mesentery here, only tissue against diaphragm
18.What are peritoneal folds?
Ans: reflection of peritoneum raised from body wall by underlying vessels,
ducts, etc. (like rug over extension cord)
19.What are lateral umbilical folds?
Ans: where the peritoneum goes over the inferior epigastric A&V; goes over
both sides (R&L)
20.What are medial umbilical folds?
Pretest - Stuvia US
, 4
Ans: fold near the midline (R&L); peritoneum covering median umbilical
AA/ligaments
21.What are median umbilical folds?
Ans: covers the median umbilical ligament (urachus)
22.What are intraperitoneal organs?
Ans: completely surrounded by visceral peritoneum
23.What are some characteristics of intraperitoneal organs?
Ans: Directly visible and accessible after one opens the peritoneal cavity -
and lifts the greater omentum- and they are mobile, as they are suspended
by ('hang from') the mesentery
24.What are some organs that are intraperitoneal?
Ans: stomach, spleen, most of small intestine (not duodenum), cecum,
appendix, transverse & sigmoid colon
25.What are retroperitoneal organs?
Ans: are outside the peritoneal cavity (space between visceral and parietal
peritoneum); they lie against posterior body wall
27.What are some organs that are retroperitoneal?
Ans: kidneys, IVC, aorta, pancreas, adrenal glands, ureters, ascending &
descending colon; the mesentery's are not covering them
