Flashcards in organization of abdomen Deck (31):
1

peritonealized organs

intraperitoneal
associated with mesentery
stomach, spleen, parts 1-4 of duodenum, jejunum, ileum, transverse and sigmoid colon

2

primary retroperitoneal

always been retroperitoneal
posterior to peritoneal
kidneys, ureters, suprarenal glands, aorta

3

secondary retroperitoneal

during development was peritonealized and associated with mesentery, later becomes retro
b/c of fusion of original mesentery and paritel peritoneum
most of duodenum, ascending, descending colon, and pancreas
easily separated surgically

4

peritonitis

inflammation of peritoneum
richly innervated by same somatic nn which innervate abdominal wall, therefore very painful and well localized
visceral peritoneum is autonomic and not well localized

5

peritoneal adhesions

fusion of various parts of peritoneal membranes
caused by inflammation, surgery, trauma, ulcers
can limit normal movement of viscera and cause chronic pain

6

mesoesophagus

associated w/final inch of esophagus

7

greater omentum

attached to greater curve of stomach
gastrocolic ligament (stomach to transverse colon)
gastosplenic ligament (stomach to spleen)
gastrophrenic ligament (fundus to diaphragm)

8

splenorenal ligament

spleen to posterior body wall near kidney

9

phrenicocolic ligament

sustentaculum lienis
diaphragm to left colic flexure

10

mesentery proper

to small intestines

11

mesoappendix

to appendix

12

transverse mesocolon

to transverse colon

13

sigmoid mesocolon

to sigmoid colon

14

dorsal mesenteries

mesoesophagus
greater omentum
spenorenal ligament
phrenicocolic ligament
mesentery proper
mesoappendix
transverse mesocolon
sigmoid mesocolon

15

ventral mesenteries

lesser omentum
falciform ligament
coronary ligaments
triangular ligaments

16

lesser omentum

from lesser curve of stomach/duodenum to liver
hepatogastric ligament
hepatoduodenal ligament

17

falciform ligametn

peritoneal attachement of liver to anterior body wall
contains ligamentum teres hepatis (remanant of umbilical v)

18

cornoary ligaments

peritoneal attachment of liver to inferior surface of diaphragm
left and right; anterior and posterior divisions

19

triangular ligaments

right and left
where anterior and posterior coronary ligaments meet

20

lesser sac

omental bursa
posterior to stomach and lesser omentum
superior recess bounded superiorly by diaphragm
inferior recess btwn 2 layers of greater omentum

21

greater sac- supracolic compartment

superior to transverse mesocolon
contains stomach, liver, spleen, gall bladder

22

greater sac-infracolic compartment

inferior to transverse mesocolon
contains small intestine, ascending colon, descending colon
separated into right and left compartments by mesentery proper

23

greater sac- paracolic gutters

right and left btwn posterolateral wall and ascending/descending colon

24

greater sac

supracolic
infracolic
paracolic gutters

25

epiploic foramen (of winslow)

communication btwn greater and lesser sacs
anterior boundary hepatoduodenal ligament
posterior IVC
superior liver
inferior first part of duodenum

26

spread of fluid to pelvic cavity

left infracolic compartment communicates freely with pelvic peritoneal cavity
right infracolic compartment prevented from moving into pelvic cavity by mesenteric proper

27

spread of fluid from paracolic gutters

right paracolic gutter open to hepatorenal and subphrenic recesses superiorly
can pool here and cause abscesses which can push through diaphragm into thoracic cavity
left closed superiorly by phrenicocolic ligament
both can drain into pelvic cavity

28

fluid from supracolic compartment

pass through epipolic foramen into lesser sac
