Liver Flashcards
What are the 5 surfaces of the liver?
• Visceral surface (Postero-inferior surface)
• Diaphragmatic surface (Superior surface )
• Anterior surface
• Posterior surface
• Right surface
The visceral surface of the liver is related to the?
- Stomach
- Esophagus
- Lesser omentum
- Gallbladder
- RCF
6. R. Kidney - R. Suprarenal gland
Rt. Lobe is divided into? By?
Divided into anterior and posterior sections by the right
hepatic vein
L. Lobe is divided by? To what?
Divided into lateral and medial segments by the left hepatic
vein
Rt. & Lt lobe separated by
• Falciform ligament
• ligamentum venosum
•Ligamentum teres
Two processes of the caudate lobe
1- Caudate process
2- Papillary process
Relations of caudate lobe
• Inferiorly - Porta hepatis
• The right - Inferior vena cava
• The left - fossa for the lig.venosum
Quad. Lobe is presented on
What’s it Relations?
The inf surface from the RT. Lobe
- Anteriorly: Ant magin of liver
- Rt: Fossa of the GB
- Lt: by the fossa gor lig.teres
Porta hepatis lies between what and what?
lies between the caudate and quadrate lobes
What attaches to the porta hepatis margin?
Lesser omentum attach to its margin
Contents of porta hepatis
• Bile duct anteriorly
• Hepatic artery in the middle
• Portal vein posteriorly
The liver is covered by peritoneum Except at?
bare area (it is origin from septum transversum)
What are The ligaments of the liver
• 1- The Falciform ligament of liver
• 2- The Ligamentum teres hepatis
• 3- The coronary ligament
• 4- The right triangular ligament
• 5- The left triangular ligament
• 6- The Hepatogastric ligament
• 7- The hepatoduonedenal ligament
Falciform ligament of liver is consisted of? Shape? It extends from?
• Consists of double peritoneal layer
• Sickle shape
• Extends from anterior abdominal wall (umbilicus) to
liver
Free border of the Falciform ligament contains?
Ligamentum teres
Ligamentum teres Umb. origin is?
obliterated umbilical vein
The area between upper and lower layer of the coronary
ligament is?
is the bare area of liver
the bare area of liver is in contact with?
diaphragm
Left and right triangular ligaments are formed by?
left and right extremity of coronary ligament
Define ligamentum venosum
Fibrous band that is the remains of the ductus venosus
Ductus venosum is attaches to?
Is attached to the left branch of the portal vein and ascends
To the IVC
The ligamentum venosum serves primarily as a?
landmark and source of controlling the left hepatic vein during dissections that require control of the bleeding
Blood supply of the liver and there branches?
- Proper hepatic artery: The right and left hepatic arteries
enter the porta hepatis - The right hepatic artery usually gives off the cystic artery, which runs to the neck of the gallbladder
Venous drainage of the liver
- The portal vein divides into right and left terminal
branches that enter the porta hepatis behind the
arteries - The hepatic veins (three or more) drain into the inferior
vena cava
Lymphatic drainage of the liver
- Lymph leave the liver and enters several lymph nod in porta hepatis efferent vessels pass to celiac nods
- A few vessels pass from the bare area of the liver through the diaphragm to the posterior Mediastinal lymph nodes
