Liver Anatomy Flashcards
define the diff between intersegmental vs intrasegmental
inter - between
Hepatic veins
hepatic veins course between the lobes and segments
intra - within
Portal Triad
portal triad courses into the center of each segment
AKA for intersegmental / interlobar vessles
hepatic veins
portal triad is encased by ____________
fibro-fatty sheath (glisssons capsule) giving it hyperechoic walls
portal triad vessles (3)
main portal vein
proper hepatic artery
common hepatic duct
the vessels of the porta hepatis are contained within what ligament
hepatoduodenal lig.
Name the hepatic fissures : (3)
main lobar fissure
right intersegmental fissure
left intersegmental fisure
the main lobar fissure divides the liver how ?
and is also refereed to as what
right and left lobes
MLF aka- cantlie line, midplane of the liver
landmarks of the MLF (3)
Gallbladder (inferior end of the MLF)
IVC
middle hepatic vein
what plane between what and what forms the MLF
oblique plane between the ivc and the galbladder fossa
the MLF divides the _____seg. of the right lobe form the _____ medial seg. of the left lobe .
anterior segment of the right lobe
medial segment of the left lobe
Right Intersegmental Fissure divides the ____ lobe into which 2 segments
right , anterior seg. and posterior seg.
what is the landmark for the right intersegmental fissure
right hep. vein
Left intersegmental fissure divides the ____ lobe of the liver ______ and _____ segs
left lobe into medial and lateral segments
Landmarks for the left intersegmental fissure
left hepatic vein
ascending left portal vein
falciform ligament
ligamentum teres
ligamentum venosum is remant of __________
ductus venosus
lig. venosum seperates what 2 structures
left lobe form the caudate lobe
ligamentum venosum is located at the ____ ____ margin of the ____ lobe
left anterior margin of the caudate lobe
ligamentum terries is located
@ left intersegmental fissure
lig. teres divides the _____ aspect of the ___lobe into _____ and _____ segments
caudal aspect of left lobe into medial and lateral segments
lig. teres is a remnant of the
umbilical vein
umbilical vein runs from _____ to _____
umbilicus to the left portal vein
what possibly happens to lig teres in cases of portal HTN
lig. teres recanalizes to form a portosystemic venous collateral
lig. venosus runs from the _______ to the ______ separtating the ________ from the ________
lft portal vein to the IVC separating the lft lobe from the caudate lobe of the liver
Direction of fetal circulation (4)
umbilical vein (teres) — lft portal vein—- ductus venosus (lig. venosum) — IVC
Falciform lig is a ________ and is created by ______–
falciform ligament is a peritoneal fold / reflection and is created by passage of the embryonic umbilival vein from the umbilicus to the left branch of the portal vein
coronary ligament is a __________ which provides what function
peritoneal reflection/fold
coronary ligament suspends the liver from the diaphragm
the coronary ligament surrounds the ______ where the _____is in direct contact with the liver
the coronary ligament surrounds the bare area,
in the bare area the diaghragm is in direct contact with the liver
the bare area is not a part of what , and therefore will not contain
peritoneal space and will not contain ascites
right & left triangular ligament are __________ and are located ______in relation to the bare area
peritoneal reflections
to the far right and left of the bare area
