Parietal and visceral peritoneum
Mesenteries of the abdominal cavity - Greater omentum
-4 layers -form an apron draping off the greater curvature of the stomach
cul de sacs -females
-anterior cul-de-sac-vesicoutrine pouch -posterior -cul -de -sac -rectouterine pouch ( of Douglas)
omental (epiploic) foramen
Opening deep to the hepatoduodenal ligament that allows for communication between the greater and lesser sacs
Retroperitoneal organs examples
adrenal gland aorta/ivc duodenum 2nd part and 3rd part pancreas ( not tail ) urteres colon kidney esophagus rectum
Mesenteries of the abdominal cavity - lesser omentum
between the liver and lesser curvature of stomach
cul de sacs
blind pouches in pelvic cavity where peritoneum dips between pelvic organs
cul de sacs -males
no uterus- retrovesicular pouch
intraperitoneal
organs entirely enclosed by visceral peritoneum
Retroperitoneal organs
organs outside the peritoneal cavity
greater sac
peritoneal compartment of the abdominal cavity that extends from the diaphragm to the pelvis and covers the width of the abdomen
peritoneal cavity
potential space between parietal and visceral layers of the peritoneum minimizes friction of visceral organs rubbing up against each other
parietal peritoneum
serous membrane that lines the walls of the abdominal cavity
visceral peritoneum
serrous membrane that reflects off the abdominal wall and can completely package a visceral organ or partially cover it
Lesser sac (omental bursa)
space of peritoneal cavity posterior to stomach and lesser omentum
Mesenteries of the abdominal cavity-transverse mesocolon
supports transverse colon from posterior abdominal wall
Mesenteries of the abdominal cavity- sigmoid
suspends sigmoid colon from posterior abdominal wall
Mesenteries of the abdominal cavity - small intestine
suspends the majority of the small intestine from the posterior abdominal wall
mesentery
where 2 layers of the visceral peritoneum meet and fuse together anchor the intra organs from the abdominal wall blood vessels, nerves and lymphatics run through the mesenteries to supply the intra organs
