II. Peritoneum- serous membrane lining the
abdomen and covering abdominal organs
A. Parietal peritoneum serous membrane lining
the inner wall of abdomen,pelvic and scrotal
cavities B. visceral peritoneum serous
membrane covering organs of abdominal and pelvic
cavities
2
C. connecting peritoneum - double-layered serous
membranes connecting parietal and visceral
peritoneums, or between visceral peritoneums inc
ludes -- mesentaries -- omentums
-- ligaments (falciform)
3
D. peritoneal cavity -- potential space
between parietal and visceral peritoneum --
contains no organs --completely closed in
male --open in female at oviduct
4
D. peritoneal cavity caudal reflections of
peritoneum forms pouches and fossas.

gut
E. retroperitoneal- term for a structure found
between peritoneum and cavity wall (thus, no
connecting peritoneum), i.e. kidney, bladder.
Also, some portions of the reproductive organs
are retroperitoneal.

Peritonitis localized or general inflammation of
the peritoneum primary- causative agents gain
access to peritoneal cavity (i.e. ovarian
bursa) secondary - as a result of trauma
(surgical wound dehiscence, hit by car,
gunshot)

The Omentum

• A double-layered connecting peritoneum between
  the stomach and abdominal organs or abdominal
  wall
• 1- Lesser omentum
• connect lesser curvature of the stomach and first
  part of duodenum to the porta of the liver
• Gastrohepatic ligament
• Hepatoduodenal ligament

The Omentum

• 2- Greater omentum
• Connect the greater curvature of the stomach to
  the dorsal abdominal wall
• Superficial leaf extend from the stomach
  caudally to pelvic inlet where it reflect and
  returns cranially as the deep leaf
• Deep leaf attaches to the dorsal abdominal wall
  and contains the left lobe of the pancreas
  between its peritoneal layers

The omentum (bovine)

• The lesser omentum arises from the visceral
  surface of the liver between the porta and the
  esophageal impression and passes to the region of
  the reticular groove, the right place of omasum ,
  and then along the lesser curvature of the
  abomasum to the first part of the duodenum

The omentum (bovine)

• The greater omentum has two leaves as in the
  other species
• Superficial leaf arises from the left side of the
  rumen and deep leaf arise from the right side of
  rumen.
• Both leaves extend ventrally and to the right,
• both leaves ascend together along the right
  abdominal wall to attach to the descending
  duodenum.

18
The omentum (bovine)

• The greater omentum has two leaves as in the
  other species
• Superficial leaf attaches the greater curvature
  of the abomasum and descending duodenum, it
  extends along the ventral abdominal wall to the
  left side to attach to the left longitudinal
  groove of the rumen.
• Deep leaf extends from the right longitudinal
  groove of the rumen to the descending duodenum

Omental bursa

• The omental sheets enclose a space (omental bursa
  is an important store of fat.
• It is completely divided from the peritoneal
  cavity except at the epiploic foramen (bursal
  foramen) near the portal of the liver.
