106b anatomy of the abdomen Flashcards
what forms the mesenteries?
splanchnopleure/visceral peritoneum
morphology of mesenteries?
simple squamous epi
in the embryo, where is the liver in relation to the stomach? the spleen?
liver and gall bladder is ventral
spleen is dorsal
which ventral mesenteries/lesser omentum break down? what does this form?
midgut and hindgut
greater peritoneal sac (abdominal cavity)
meckel’s diverticulum
blind sinus with all 3 gut wall laters (mucosa, submucosa, muscularis externa) that is attached to umbilicus via a fibrous cord
what forms the lesser peritoneal sac (aka omental bursa)?
dorsal mesentery/dorsal mesogastrium/greater omentum to the left as the stomach and liver rotates right
what is the communicaiton between the lesser and great sacs?
epiploic foramen of winslow
Falcifrom
1) connects
2) structures contained
3) notes
1) connects: liver and anterior ab wall
2) structures contained = ligamentum teres hepatis
3) notes - from ventral mesentery
hepatoduodenal
1) connects
2) structures contained
3) notes
1) connects = liver and duodenum
2) structures contained = portal triad (hepatic artery, portal vein, common bile duct)
3) notes = connects greater and lesser sacs; from lesser omentum
hepatogastic
1) connects
2) structures contained
3) notes
1) connects = liver and lesser curve of stomach
2) structures contained = gastric arteries
3) notes = seperates greater and lesser sacs on right, cut to access lesser sac; from lesser omentum
gastrocolic
1) connects
2) structures contained
3) notes
1) connects= greater curve and trasnverse colon
2) structures contained = gastroepiploic arteries
3) notes = part of greater omentum; adhesion
gastrosplenic
1) connects
2) structures contained
3) notes
1) connects= greater curve and spleen
2) structures contained
3) notes = seperates greater and less sac on left
splenorenal
1) connects
2) structures contained
3) notes
1) connects= spleen and posterior ab wall
2) structures contained= spelnic artery and vein; tail of pancreas
3) notes
what is formed from the ventral mesogastrium?
falciform ligament
coronoary ligament
lesser omentum (heptogastric and hepatoduodenal)
what is formed from the dorsal mesogastrium?
greater omentum
gastosplenic ligament
splenorenal ligament
