Serrat - Peritoneum Flashcards
The main and larger part of the peritoneal cavity; begins at diaphragm and continues inferiorly to pelvic cavity
What is entered when the parietal peritoneum is penetrated
Greater sac
The lesser sac lies posterior to the stomach and adjoining structures. It communicates with the greater sac thru the ________
Epiploic foramen
Lesser sac is also called the ?
Omental bursa
The sac that is posterior to the stomach and adjoining structures, communicates with other sac thru epiploic foramen
Omental bursa (lesser sac)
Structures that are completely encased in peritoneum and suspend from abdominal wall by mesenteries.
Intraperitoneal
These organs invaginate the peritoneal cavity
Structures that lie outside the peritoneum with only one surface touching peritoneum. Not suspended in abd cavity
Retroperitoneal structures
Organs that develop and remain between the peritoneum and body wall
Primary retroperitoneal
Organs that develop w/in the peritoneum but later fuse w/ the body wall
Secondary retroperitoneal organs
Double layer of peritoneum that suspends viscera from the posterior part of the Anterior body wall
Mesentery
Attaches viscera to the posterior abdominal wall
Found in foregut, midgut and most o hind gut
Dorsal mesentery
Named parts of the dorsal mesentery
Greater omentum
“The mesentery proper”
Mesoappendix
Transverse mesocolon
Sigmoid mesocolon
The mesentery of jejunum and ileum that is a large fan shaped mesentery that attaches the 20 foot of small intestine to a 15-20cm root on the posterior abdominal wall.
Directed obliquely from upper left to lower right
the mesentery proper
Attaches viscera to anterior abd wall. Limited to the terminal esophagus, stomach and proximal duodenum
Develops in assoc w/ growth of liver and hence the named parts of the ___ are connected to the liver
Ventral mesentery
The _____ provide pathways for the flow of ascitic fluid and the spread of intraperitoneal infections
Paracolic gutters
What are the 4 peritoneal gutters
?
Right of the mesentery (infracolic)
Left of the mesentery (infracolic)
Right lateral (paracolic)
Left lateral (paracolic)
The space in the greater sac between the diaphragm and liver on either side of the falciform ligament
Subphrenic recess
Part of the greater sac between the liver and right kidney and diaphragm
Lowest part of the abdominopelvic cavity when pt is lying down
Hepatorenal recess
Specific peritoneal ligaments of the stomach
Double layered folds of peritoneum that pass from stomach and prox duodenum to adjacent viscera in abd cavity or abd wall
Omenta
The fatty structure overlying the organs
Greater omentum
Connects lesser curvature of the stomach and proximal duodenum to the liver
Lesser omentum
This connects the proximal duodenum and lesser curvature of the stomach with the liver
Consists of hepatogastric and hepatoduodenal ligaments
(Hepatoduodenal ligament contains in it the portal triad)
Lesser omenutm
Connection between the liver and the anterior abdominal wall. The free edge contains ligamentum teres (which is obliterated umbilical vein)
Formed by ventral mesentery.
Falciform ligament
Connects liver to diaphragm
Coronary ligament
Triangular ligaments
Hangs down like an apron from greater curvature of stomach and proximal duodenum; descends and then folds back to attach to anterior part of the transverse colon and its mesentery
(Named parts are the gastrophrenic ligament, gastrosplenic ligament, and gastrocolic ligament)
Greater omentum
Inflammation of the peritoneum that occurs from injury or infection
Peritonitis
The lateral edge of the _________ ligaments marks the epiploic foramen
Hepatoduodenal
