29
greater omentum
binds against stomach; holds infections in place
30
where greater and lesser omentum bind
lesser sac
31
LARP
left vagus: anterior (to esophagus); right vagus: posterior (to esophagus)
32
order of intestinal folding
straight; herniate; rotate; squish(ilate)
33
what goes with intestinal mesentery during rotation
nerve supply
34
lesser sac aka
omental bursa
35
greater sac
peritoneal sac
36
epiploic/omental foramen function
communicates between lesser and greater sacs
37
intraperitoneal
completely enclosed in visceral peritoneum
38
intraperitoneal structures
liver, gall bladder, spleen, stomach, 1st part of duodenum, jejunum, ileum, vermiform appendix, transverse colon, sigmoid colon
39
primarily retroperitoneal
anterior surface covered by parietal peritoneum - no gut rotation, so posterior/dorsal to peritoneum
40
primarily retroperitoneal structures
kidney, adrenal, inferior vena cava, aorta, testis
41
secondarily retroperitoneal
adherent to posterior peritoneal wall
42
secondarily retroperitoneal structures
2nd 3rd 4th parts of duodenum, cecum, ascending colon, descending colon, rectum, pancreas
43
extraperitoneal
outside peritoneum, but not posterior or dorsal
44
extraperitoneal structures
urinary bladder, prostate, seminal vesicles, uterus, ovary
45
derivatives of ventral mesentery
ventral mesogastrum - lesser omentum (hepatoduodenal, hepatogastric), falciform, coronary, right triangular, left triangular
46
hepatoduodenal ligament contains
portal vein, hepatic artery, bile duct
47
obligterated umbilical vein is
ligamentum veres hepatis, falciform ligament
48
dorsal mesentery derivatives
dorsal mesogatrum, mesentery of small intestine, mesenteries of large intestine (colon)
49
dorsal mesogastrum derivatives
greater omentum, adult transver mesocolon, lienorenal or phrenicolineal ligament
50
greater omentum derivatives
gastrophrenic (stomach-diaphragm); gastrolienal (stomach-spleen); gastrocolic (stomach-transverse colon)
51
mesenteries of large intestine- derivatives
transverse mesocolon, sigmoid mesocolon, mesoappendix
52
upper/superior recess location
within lesser omentum
53
lower/inferior recess location
within greater omentum
54
what does lesser omentum attach to
lesser curvature of stomach; forms part of lesser sac walls
55
what does greater omentum attach to
greater curvature of stomach; but NOT THE GREATER SAC
56
layers of greater omentum
2 layers in gastrophrenic/gastrolineal portions
4 layers in gatrocolin portion (double layer, folded on itself)
6 layers where embryonic transverse mesocolon (2 layers) adheres
57
parietal peritoneum derivatives
secondary mesenteries
58
ligament
any suspender not called a "mesentery"- usu peritoneal folding containing blood vessels, unrelated to embryonic gut suspension
59
