腹膜The peritoneum
海南医学院 解剖教研室
易西南
概貌General features




The peritoneum is a thin serous
membrane that line the inner surface of
the abdominal wall and pelvic cavities and
cover the organs within these cavities
Parietal peritoneum 壁腹膜
-lines the inner surface the abdominal
and pelvic wall
Visceral peritoneum 脏腹膜
-covers the organs
Peritoneal cavity 腹膜腔-the potential
space between the parietal and visceral
layer of peritoneum, in the mail, is a closed
sac, but in the female, there is a
communication with the exterior through
the uterine tubes, the uterus, and the
vagina
功能Function



Secretes a lubricating
serous fluid(润湿)
Absorb(吸收)
Support the visceras(支持)
脏器与腹膜的关系

腹膜内位器官Intraperitoneal viscera -viscera completely
surrounded by peritoneum, example, stomach, superior
part of duodenum, jejunum, ileum, cecum, vermiform
appendix, transverse and sigmoid colons, spleen and ovary

腹膜间位器官Interperitoneal viscera -most part of
viscera surrounded by peritoneum, example, liver,
gallbladder, ascending and descending colon, upper part of
rectum, urinary bladder and uterus

腹膜外(后)位器官Retroperitoneal viscera -some organs
lie on the posterior abdominal wall and are covered by
peritoneum on their anterior surfaces only, example, kidney,
suprarenal gland, pancreas, descending and horizontal parts
of duodenum, middle and lower parts of rectum, and ureter


右Right-网膜孔
omental foramen
The Omental bursa (lesser sac)
communicates with the greater
sac through the omental
foramen.
肠系膜Mesenteries -
two-layered fold of peritoneum that
attach part of the intestines to the
posterior abdominal wall
肠系膜Mesentery -




suspends the small
intestine from the posterior
abdominal wall
Broad and a fan-shaped
Consists of two peritoneal
layers
Intestinal border-folded, 7
m long
Root of mesentery


15 cm long
Directed obliquely from
left side of L2 to in front
of right sacroiliac joint
阑尾系膜Mesoappendix
 Triangular mesentery-
extends from terminal part
of ileum to appendix
 Appendicular artery runs
in free margin of the
mesoappendix
横结肠系膜Transverse mesocolon
-a double fold of peritoneum
which connects the transverse
colon to the posterior abdominal
wall
乙状结肠系膜Sigmoid mesocolon
-inverted V-shaped, with apex
located in front of left ureter and
division of common iliac artery
韧带Ligaments -two-layered
folds of peritoneum that attached
the lesser mobile solid visera to
the abdominal wall
Ligaments of liver


腹膜腔的分区Peritoneal cavity subdivisions
The transverse colon and transverse mesocolon divides
the greater sac into supracolic and infracolic
compartments.

右结肠旁沟Right paracolic sulcus -lies
lateral to the ascending colon. It
communicates with the hepatorenal
recess and the pelvic cavity. It provides a
route for the spread of infection between
the pelvic and the upper abdominal region.
左结肠旁沟 Left paracolic sulcus -lies
lateral to the descending colon. It is
separated from the area around the
spleen by the phrenicocolic ligament, a
fold of peritoneum that passes from the
colic flexure to the diaphragm.

mesocolon, its widens below where
it is continuous with the cavity of the
pelvis
