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 membran
e 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 serou
s 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, ex
ample, 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

腹膜形成的结构 Structures which are formed by peritoneum 网膜 Omentum - two-layered fold of peritoneum that ex
tends from stomach to adjacent organs
小网膜 Lessor omentum - two-layered fold of peritoneum which extends from porta hepatis to lesser curvature of stomach and superior part of duodenum
肝胃韧带 Hepatogastric ligament
- extends from porta hepatis to lesser curvature of stomach
肝十二指肠韧带 Hepatoduodenal ligament
Extends from porta hepatis to superior part of duodenum. Contains common bile duct胆总管 , proper hepatic a肝固有动脉 . and hepatic portal v门静脉 .

肠系膜 Mesentery - suspends the small intestine from the posterior abdominal wall

冠状韧带 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

腹膜腔的分区 Peritoneal cavity subdivisionsThe transverse colon and transverse mesocolon divides
the greater sac into supracolic and infracolic compartments.
结肠上区 Supracolic compartments (subphrenic space) - lies between diaphragm and transverse colon and transverse mesocolon
肝上间隙 Suprahepatic recess 左肝上 右肝上
肝下间隙 Infrahepatic recess 右肝下 左肝下:左肝下前 左肝下后(网膜囊)
结肠下区 Infracolic compartments - lies below the transverse colon and transverse mesocolon
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.
右肠系膜窦 Right mesenteric sinus - triangular space, lies betwe
en root of mesentery, ascending colon, right 2/3 of transverse colon and transverse mesocolon
左肠系膜窦 Left mesenteric sinus - lies between root of mesentery, descending colon, right 1/3 of transverse colon and transverse mesocolon, its widens below where it is continuous with the cavity of the pelvis
