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
