Flashcards in Peritoneal Relations Deck (18):
0

Greater Sac

Main part of peritoneal cavity that begins at the diaphragm and continue to the pelvic cavity

1

Omental Bursa

"Lesser Sac"

Lies posterior to the stomach and adjoining structures; communicates w/ the greater sac via teh epiploic foramen

2

Superior Recess

Limited superiorly by the diaphragm and the coronary ligament of the liver

3

Inferior Recess

B/w the superior part of the layers of the Greater Omentum

4

Secondary Retroperitoneal Organs

Duodenum, pancreas, ascending/descending colon

5

Medial Umbilical Fold

Obliterated Urachus

6

Medial Umbilical Folds

Obliterated Umbilical Arteries

7

Lateral Umbilical Folds

Inferior Epigastric Vessels

8

"The Mesentary"

Referes to the greater omentum

9

Paracolic Gutters

Found lateral to the ascending/descending colon; potential pathways for flow of ascitic fluid and spread of intraperitoneal infxns

10

Subphrenic Recess

Lies in the space b/w the diaphragm and liver on either side of the falciform ligament

11

Hepatorenal recess

Found b/w the liver and the R. kidney; bacterial infected fluids could flow to this recess thru the epiploic foramen or from anywhere in the greater sac

*Commonly assoc. w/ infxn of the pleural cavity

12

Lesser omentum

Connects lesser curvature of the stomach to the duodenum and liver

*Includes the hepatogastric and hepatoduodenal ligaments

*Also contains the PORTAL TRIAD

13

Falciform ligament

Connection b/w the anterior abdominal wall and liver; formed by ventral mesentary

Contains ligamentum teres

14

Greater Omentum

Hangs like an apron from the greater curvature of the stomach and folds back to attach to the transverse colon; dorsal mesentary ligament

*Contains the gastrophrenic, gastrosplenic, and gastrocolic ligaments

15

Peritonitis

Inflammation of the peritoneum that can lead to excess fluid accumulation

16

Peritoneal adhesions

Fibrous bands of scar tissue b/w organs that are most commonly caused by surgery

*Can cause intestinal blockage

17

Structures developed from ventral mesentary

Triangular ligaments
Falciform ligament
Coronary Ligament
Lesser omentum
