anatomy of peritoneum and the peritoneal cavity. the modification of peritoneum and the structures associated with peritoneum such as, omentum, mesentry mesocolon, epiploic foramen, pouches, peritoneal ligaments, and folds and recesses.

1. PERITONEUM
DR SANA YASEEN
ANATOMY DEPT.

2. INTRODUCTION
Is the largest
serous membrane
in the body, lining
the body cavity .
DIVISIONS:
Parietal layer
Visceral layer

3. PERITONEAL CAVITY
 Potential space between the parietal and visceral peritoneum
Containing small amount of fluid
In male: closed sac
Female : open sac via uterine tube, uterus, vagina
Functions:
1. Allows mobility
2. Lubricates the visceras

4. SUBDIVISION
OF
PERITONEUM
GREATER SAC
LESSER SAC/
OMENTAL BURSA

6. STRUCTURES FORMED FROM PERITONEUM
*Omentum.
*Mesenteries / mesocolon
*Peritoneal ligaments
*Folds and recesses
*Pouches

7. OMENTUM
 Two layered fold extending from stomach to other organs
GREATER OMENTUM
LESSER OMENTUM

9.  Four layered fold
extending from
greater curvature of
stomach infront of
anterior part of
intestine then coils
itself and gets attach
to transverse colon

10. LESSER OMENTUM
Two layered fold extend
from porta hepatis to
lesser curvature of
stomach and superior
part of duodenum
Hepatogastric
ligament
Hepatoduodenal
ligament

12. EPIPLOIC
FORAMEN
 Also know
as foramen
of
WINSLOW

13. Boundaries
ANTERIOR: hepatoduodenal ligament (free edge of lesser
omentum) containing portal traid
POSTERIOR: IVC, R-supra renal gland, T12 vessels covered
by peritoneum anterior
SUPERIORLY: caudate process of liver
INFERIORLY: First part od duodenum, hepatic artery

15. MESENTERY
 Suspends
intestine from
the posterior
abdominal wall

16. SMALL INTESTINE MESENTRY

18. MESOAPPENDIX
Small triagular
shape mesentry
Extending from
terminal part of
ileum to appendix

20. The term refers mainly to the spaces in the abdominal cavity;
including
 Two paracolic gutters and
 Two paramesenteric gutters.
o There are other smaller recesses including those around the
duodenojejunal flexure, cecum and the sigmoid colon.
RECESS

22. Small RECESS
Duodenal recess
oSuperior duodenal recess
oInferior duodenal recess
oParaduodenal recess
oRetroduodenal recess
oDuodenojejunal recess
oMesenteroperitoneal
recess
Cecal recess
oSuperior iliocecal
recess
oInferior ilioceacal
recess
oRetrocaecal recess
Intersigmoid recess

23. DUODENAL
RECESSES

24. CEACAL
RECESSES

25. INTERSIGMOID RECESS

26. PERITONEAL LIGAMENTS
Falciform ligament
Coronary ligament
R&L ligament
Hepatoduodenal ligament

Gastrocolic ligament
Gastropancreatic ligament
Ligament of stomach

27. LIGAMENTS
OF LIVER

SPLEEN

31. POUCHES
In male－rectovesical
pouch
In female
◦ Rectouterine pouch －
between rectum and uterus
◦ Vesicouterine pouch －
between bladder and uterus

between viscera
and peritoneum
