peritoneal cavity

potential space
between int abdominal wall and pelvic wall (parietal peritoneum) and lining of abdominal organs (visceral peritoneum)
blood supply from nearby abd wall vessels, visceral peritoneum receives blood from overlying organ

median umbilical fold

fetal urachus
from pubic symphysis to umbilicus

medial umbilical fold

fibrous cord of obliterated umbilical artery

lateral umbilical fold

overly inferior epigastric artery and vein

mesentery/ligament/omentum

folding of visceral peritoneum forms double layer

greater omentum

drapes over abd organs
gastrocolic, gastrosplenic, gastrophrenic ligaments

lesser omentum

between liver and lesser curvature of stomach
hepatoduodenal and hepatogastric ligaments

lesser sac/omental bursa

posterior to stomach, communicates with greater sac via omental foramen (this is posterior to free edge of lesser omentum)
perforation of the posterior stomach wall (ulcer) or pancreatic inflammation causes gastric contents or pancreatic fluid to leak into lesser sac
loop of small intestine can enter lesser sac and become strangulated

epiploic foramen boundaries

hepatoduodenal lig (contains portal triad)
IVC
caudate lobe of liver
1st part of duodenum

intraperitoneal/mobile organs

stomach
1st duodenum
liver
jejunum
ileum
appendix
transverse, sigmoid colon

retroperitoneal/immobile

rest of duodenum
cecum
ascending colon
descending colon

stomach

rests on stomach bed: transverse colon, spleen, body and tail of pancreas, splenic artery, anterior surface of left kidney, left adrenal gland

gastrophrenic ligament

peritoneal fold connecting fundus to diaphragm

gastrosplenic lig

connects greater curvature to spleen

gastrocolic

fold of greater omentum that passes from stomach to transverse colon

left gastric a

from celiac trunk
in lesser omentum to stomach, runs along lesser curvature
anastomoses w right gastric a
25%: l gastric a gives aberrant left hepatic a, supplies left lobe liver

right gastric a

from proper hepatic a
along lesser curvature near pyloric portion
anastomoses w l gastric a

l gastroepiploic a

from splenic a
in gastrosplenic lig
along greater curvature
anastamoses w r g a

r gastroepiploic a

along greater curvature
anastomoses w l ge a

short gastric a

from splenic a
in gastrosplenic lig
runs along upper greater curvature of stomach

dorsal gastric a

from splenic a
supplies dorsal surface of stomach
not in all persons

l and r gastric veins

drain into portal vein

l ge vein

drains into splenic vein

r ge vein

drains into SMV

innervation

SNS: greater splanchnic n, pass through diaphragm, synapse w celiac plexus
PNS: anterior and posterior vagal trunks, controls acid secretion

small intestine

duodenum, jejunum, ileum
duodenum: shortest, widest, most fixed, foregut
ducts from liver (common bile duct) and pancreas (main pancreatic duct)
only 1st part of duodenum is not intraperitoneal

descending duodenum

descends along l1-l3 vertebral bodies
head of pancreas touches medial descending duodenum
common bile duct and main pancreatic duct empty here

horizontal/3 duodenum

passes over IVC, aorta, l3
SMA and SMV pass anterior to horizontal duodenum

ascending/4 duodenum

ascends on l side of aorta to l2 vertebral body
ascending duodenum makes acute angle to join jejunum at duodenuojejunal flexure
contraction of suspensory muscle facilitates movement of intestinal contentsby widening angle of duodenojejunal flexure

gastroduodenal a

terminal branch of common hepatic a
gives rise to anterior and posterior superior pancreaticoduodenal arteries that supply duodenum proximal to entry of common bile duct
gives off supraduodenal a that supplies duodenum

SMA

gives a and p inferior pancreaticoduodenal a, supply duodenum distal to common bile duct

liver

largest gland of body
bare area: no visceral covering, where IVC is found
visceral surface contacts: gall bladder, ascending and transverse colon, duodenum, stomach, right kidney and adrenal gland
bare at bed of gallbladder and porta hepatis (doorway)

falciform ligament

double layer peritoneum
connects liver w diaphragm and ant abdominal wall
formed from ventral mesentery
separate r and l lobe

round ligament

free edge of falciform
remains of l umbilical vein

coronary lig

peritoneal covering of superior surface of liver
tent over liver
area under is bare area

caudate lobe

posteroinferior surface of liver

quadrate lobe

anteroinferior surface

common hepatic a

from celiac trunk
gives gastroduodenal a
becomes proper hepatic a
divides into r and l hepatic a

portal vein

union of SMV and splenic V
carries nutrients absorbed from intestine
divides into r and l portal v

hepatic v

drains liver sinusoids from portal veins, into IVC

portal triad

common hepatic duct, proper hepatic artery, portal vein

common hepatic duct

formed by union of r and l hepatic ducts from liver
unites w cystic duct from gallbladder forming common bile duct

gallbladder

inferior visceral surface of liver
fundus at right 9th costal cartilage
neck: spirals into valve, ends in cystic duct

cystic triangle

liver, cystic duct, and common hepatic duct
cystic artery within

pancreas

retroperitoneal (mobile)
posterior to stomach
head: expanded part of pancreas that lies in duodenal curve
uncinate process extends medially to the left
SMV and SMA are superficial to uncinate process
neck overlies SM vessels
body: extends left across aorta and l2
splenic a and v run above or in body of pancreas
tail: narrowed portion of pancreas, touches hilum

main pancreatic duct

begins in tail of pancreas
runs through pancreas to join common bile duct before entering 2nd part of duodenum as the hepatopancreatic ampulla

accessory pancreatic duct

drains head of pancreas and opens separately into duodenum superior to main duct opening

great pancreatic artery

from splenic a
near junction of body and tail of pancreas

dorsal pancreatic a

from splenic a
near origin of splenic a
to neck of pancreas

pancreaticoduodenal a

a and p
superior: branches of gastroduodenal a
inferior: SMA branches
supply head of pancreas

spleen

large lymphatic organ in ULQ
