organization of abdomen

Question 1

peritonealized organs

Answer 1

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

Question 2

primary retroperitoneal

Answer 2

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

Question 3

secondary retroperitoneal

Answer 3

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

Question 4

peritonitis

Answer 4

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

Question 5

peritoneal adhesions

Answer 5

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

Question 6

mesoesophagus

Answer 6

associated w/final inch of esophagus

Question 7

greater omentum

Answer 7

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

Question 8

splenorenal ligament

Answer 8

spleen to posterior body wall near kidney

Question 9

phrenicocolic ligament

Answer 9

sustentaculum lienis

diaphragm to left colic flexure

Question 10

mesentery proper

Answer 10

to small intestines

Question 11

mesoappendix

Answer 11

to appendix

Question 12

transverse mesocolon

Answer 12

to transverse colon

Question 13

sigmoid mesocolon

Answer 13

to sigmoid colon

Question 14

dorsal mesenteries

Answer 14

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

Question 15

ventral mesenteries

Answer 15

lesser omentum
falciform ligament
coronary ligaments
triangular ligaments

Question 16

lesser omentum

Answer 16

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

Question 17

falciform ligametn

Answer 17

peritoneal attachement of liver to anterior body wall

contains ligamentum teres hepatis (remanant of umbilical v)

Question 18

cornoary ligaments

Answer 18

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

Question 19

triangular ligaments

Answer 19

right and left

where anterior and posterior coronary ligaments meet

Question 20

lesser sac

Answer 20

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

Question 21

greater sac- supracolic compartment

Answer 21

superior to transverse mesocolon

contains stomach, liver, spleen, gall bladder

Question 22

greater sac-infracolic compartment

Answer 22

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

Question 23

greater sac- paracolic gutters

Answer 23

right and left btwn posterolateral wall and ascending/descending colon

Question 24

greater sac

Answer 24

supracolic
infracolic
paracolic gutters

Question 25

epiploic foramen (of winslow)

Answer 25

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

Question 26

spread of fluid to pelvic cavity

Answer 26

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

Question 27

spread of fluid from paracolic gutters

Answer 27

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

Question 28

fluid from supracolic compartment

Answer 28

pass through epipolic foramen into lesser sac

Question 29

celiac a

Answer 29

T12

Question 30

SMA

Answer 30

L1

Question 31

IMA

Answer 31

L3
