What is in contact with the posterior border of the liver? 8
Aorta, gallbladder, right Kidney, inferior vena cava, portal vein confluence, colon, cystic duct, hepatic artery
What does the falciform ligament do to liver?
Suspense liver from the diaphragm and the anterior abdominal wall
What does the reflections of diaphragm do?
Suspense liver from the diaphragm
What is bare area?
It’s the area of the liver that is not covered by peritoneum
Where do abscesses usually form?
In subphrenic area between liver/spleen, and diaphragm or the lesser sac
Where is the right posterior subphrenic space located?
In between the right lobe of the liver, the right kidney and the right colic flexure
Where is the lesser sac located in relationship to the liver/stomach?
Posterior
Where is the Right subhepatic space located and what does it include?
The Right subhepatic space is located inferior to the right lobe of the liver and includes the Morrison pouch
Where is the Morisons pouch located in relationship to the liver ?
Posterior to the right lobe and upper pole of the right kidney 
What does the falciform ligament attachment do? Within
It divides the liver into right and left lobes
What does the gallbladder do in relationship to the liver?
It divides the right lobe into the quadrant lobe and caudate lobe
What does the IVC do in relationship to the liver
Divides the right lobe into the quadrate lobe and the caudate lobe
What does the ligamentum teres and ligamentum venosum do in relationship to the liver
Divides the right lobe into the quadrate lobe and the caudate lobe
What is it called when there is a functional division of the liver?
Vasculature
What divides the liver into right and left lobes functionally
Middle hepatic vein and ascending section of the left portal vein
Where is the quadrate lobe located veins
Between middle and left hepatic veins
Quadrate lobe is part of ….
Medial segment of the left lobe
What are the eight segments of the liver?
- Caudate lobe
- left lateral superior
- left lateral inferior
- left medial superior and inferior
- right anterior inferior
- right posterior inferior
- right posterior superior
- right anterior superior
Where is the right lobe of the liver located?
Within the right hypochondrium
How larger is the right lobe compared to the left
Six times larger
What are the inferior and posterior surface of the right lobe of the liver marked by
Three Fossae: porta hepatis, gallbladder fossa, and Ivc fossa
What vein runs horizontally between the anterior and posterior segment of the right lobe
Right hepatic vein
Where is the left lobe of the liver located?
Within the left hypochondrium, and in the epigastric
What is the left lobe divided into and by what?
Left lobe of the liver is divided into medial and lateral segments by the left intersegmental fissure 
How is the left lobe bounded to porta hepatis
Posteriorly
How is the left lobe bounded to gallbladder fossa
Medially
How is the liver bounded to umbilical vein
Laterally
What are the two fissures of the left lobe
Ligamentum teres, ligamentum venosum 
Where is the caudate lobe located?
Posterior to left lobe
What is the posterior border of the caudate lobe
Ivc
What is the anterior border of the caudate lobe
Ligamentum venosum
What does the left margins of the caudate lobe form
Hepatic boundary of the superior recess of the lesser sac
How does the caudate process travel / in between what
Extends obliquely and laterally from the caudate lobe and a course is to the right lobe in between portal vein and ivc
How does the right hepatic vein course
Within the right intrasegmental fissure that divides the right lobe of the liver into the anterior and posterior segments 
How does the middle hepatic vein course?
Within main lobar fissure to separate anterior segment of the right lobe from the medial segment of the left lobe
What does the left intrasegmental fissure do?
Separates medial segment of the left lobe from lateral segment. It also divide middle cranial and caudal sections
In left intersegmental fissure what forms the bound of cranial third
Left hepatic vein
In left intersegmental fissure what bounds the middle section
Ascending branch of left portal vein
In Left intersegmental fissure what bounds caudal section
Ligamentum teres
What is the echogenicity of the ligaments in the liver and why?
Hyperechoic bc of collagen and fat
Whats the glissons capasule
Thin ct that covers liver
Where is the glissons capsule the thickest
Around ivc and portal hepatis
What does the hepatoduodenal ligament contain
Mpv, proper hepatic artery and common duct
Whats the main lobular fissure
Its the boundary between the right and left lobes of the liver
Whats the echogenecity of the main lobular fissure/where is it located
Hyperechoic line from portal vein to neck of gallbladder
Where does the falciform ligament extend from and to
From umbilicus to diaphragm
What does the falciform Ligament (vertical) contain
Ligamentum teres (vertical)
What does the ligamentum venosum seperate
Left lobe from caudate lobe (horizontal)
