Download The peritoneum

SAILENT FEATURES




Peritoneum is a serous membrane
that line the walls of the abdominal
and pelvic cavities and cover the
organs within these cavities
Parietal peritoneum －lines the
walls of the abdominal and pelvic
cavities
Visceral peritoneum －covers the
organs
Peritoneal cavity －the potential
space between the parietal and
visceral layer of peritoneum.
Function Of Peritoneum
 Secretes
a serous fluid that continuously
moistens the associated organs.
 Support
viscera
Interperitoneal viscera
 Relation
of
peritoneum in male
pelvis.
Omentum
two-layered fold of
peritoneum that
extends from
stomach and first part
of Duodenum to
adjacent organs
Lessor omentum


－two-layered fold of
peritoneum which extends
from porta hepatis (Liver)
to lesser curvature of
stomach and first part of
duodenum
Hepatogastric ligament
－extends from porta
hepatis to lesser curvature
of stomach
Hepatoduodenal
ligament
Extends from
porta hepatis to first part of
duodenum
Omental foramen
(Foramen of
Winslow)





Behind the right free
margin of hepatoduodenal
ligament
Superiorly－caudate lobe
of liver
Inferiorly First part of
duodenum
Anterior－hepatodudenal
ligament
Posterior－peritoneum
covering the inferior vena
cava
Greater omentum
－four-layered fold. The
anterior two layers descend
from the greater curvature of
stomach and First part of
duodenum and hangs down
like an apron turns upward
and attaches to the
transverse colon..
Position－situated beyond and behind
the lesser omentum and stomach
Mesentery－two-layered
fold of peritoneum that
attach part of the intestines
to the posterior abdominal
wall
Mesentery
－suspends the small
intestine from the
posterior abdominal wall
 Broad and a fan-shaped
 Consists of two
peritoneal layers
 Intestinal border－folded,
6-7 m long
 Root of mesentery
• 15 cm long
• Directed obliquely from
left side of L2 to in front
of right sacroiliac joint
Ligaments of Liver
－two-layered folds of
peritoneum that attached
the lesser mobile solid
visera to the abdominal
wall
Ligaments of liver

Falciform ligament of
liver
• Consists of double
peritoneal layer
• Extends from anterior
abdominal wall (umbilicus)
to liver
Coronary ligament
－the area between
upper and lower parts of
the coronary ligament is
the bare area of live, this
area is devoid of
peritoneum and lies in
contract with the
diaphragm
 Left and right
triangular ligaments
－formed by right
extremity of coronary
ligament and left leaf of
falciform ligament,
respectively




Hepatogastric ligament
Hepatoduodenal
ligament
Ligamentum teres
hepatis
Ligaments of stomach





Hepatogastric ligament
Gastrosplenic ligament
Gastrophrenic ligament
Gastrocolic ligament
Gastropancrestic ligament



Medial umbilical fold －
contain the remnant of
urachus (median umbilical
ligaments)
Medial umbilical fold －
contains remnants of the
umbilical arteries (medial
umbilical ligaments)
Lateral umbilical fold －
contains the inferior
epigastric vessels
Pouches
 In
male－
rectovesical pouch
 In female
• Rectouterine pouch
－between rectum and
uterus
• Vesicouterine pouch
－between bladder
and uterus
