Flashcards in 106b anatomy of the abdomen Deck (16):
1

what forms the mesenteries?

splanchnopleure/visceral peritoneum

2

morphology of mesenteries?

simple squamous epi

3

in the embryo, where is the liver in relation to the stomach? the spleen?

liver and gall bladder is ventral
spleen is dorsal

4

which ventral mesenteries/lesser omentum break down? what does this form?

midgut and hindgut
greater peritoneal sac (abdominal cavity)

5

meckel's diverticulum

blind sinus with all 3 gut wall laters (mucosa, submucosa, muscularis externa) that is attached to umbilicus via a fibrous cord

6

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

7

what is the communicaiton between the lesser and great sacs?

epiploic foramen of winslow

8

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

9

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

10

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

11

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

12

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

13

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

14

what is formed from the ventral mesogastrium?

falciform ligament
coronoary ligament
lesser omentum (heptogastric and hepatoduodenal)

15

what is formed from the dorsal mesogastrium?

greater omentum
gastosplenic ligament
splenorenal ligament

16

what are the retroperitoneal structures? (These are superficial to the parietal peritoeneum)

SAD PUCKER
Suprarenal (adrenal) gland
Aorta and IVC
**Duodenum (2nd and 3rd parts)
**Pancreases (except tail)
Ureters + Bladder
**Colon (descending and ascending)
Kidneys
Esophagus (lower 2/3rds)
Rectum (lower 2/3rds)
**=secondarily retroperitoneal from fusion of greater omentum
