Peritoneal Relations Flashcards
Omental Bursa
“Lesser Sac”
Lies posterior to the stomach and adjoining structures; communicates w/ the greater sac via teh epiploic foramen
Greater Sac
Main part of peritoneal cavity that begins at the diaphragm and continue to the pelvic cavity
Superior Recess
Limited superiorly by the diaphragm and the coronary ligament of the liver
Inferior Recess
B/w the superior part of the layers of the Greater Omentum
Secondary Retroperitoneal Organs
Duodenum, pancreas, ascending/descending colon
Medial Umbilical Fold
Obliterated Urachus
Medial Umbilical Folds
Obliterated Umbilical Arteries
Lateral Umbilical Folds
Inferior Epigastric Vessels
“The Mesentary”
Referes to the greater omentum
Paracolic Gutters
Found lateral to the ascending/descending colon; potential pathways for flow of ascitic fluid and spread of intraperitoneal infxns
Subphrenic Recess
Lies in the space b/w the diaphragm and liver on either side of the falciform ligament
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
Lesser omentum
Connects lesser curvature of the stomach to the duodenum and liver
- Includes the hepatogastric and hepatoduodenal ligaments
- Also contains the PORTAL TRIAD
Falciform ligament
Connection b/w the anterior abdominal wall and liver; formed by ventral mesentary
Contains ligamentum teres
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
