Liver and gallbladder Flashcards
How many surfaces does the liver have?
5: Ant, post, sup, inf, right
Divided into right and left lobes by
Ant and sup: falciform
Inf: Ligamentum teres
Post: ligamentum venosum
Right lobe
Larger than left, caudate and quadrate lobes
Caudate
- post surface
- right: IVC
- left: fissure for ligamentum venosum
- inf: porta hepatis
- conn to right lobe by caudate process
Quadrate
- inferior surface
- rectangular
- ant: inferior border
- right: fossa for gall bladder
- left: fissure for ligamentum teres
Porta hepatis
- portal vein and hepatic artery
- hepatic plexus of nerves enters
- hepatic ducts leave
- VAD: (post to ant)- portal vein, hepatic artery, bile ducts
- lesser omentum attaches to lips of porta hepatis
Left lobe
- smaller than right
- rounded elevation near fissure for ligamentum venosum: omental tuberosity
Areas not covered by peritoneum
- bare area on post surf of right lobe
- groove for IVC
- fossa for gall bladder
- porta hepatis
Falciform lig
Att anterosup surface of liver to anterior abdominal wall and to under surface of diaphragm
Left triangular
Conn sup surface of left lobe of liver to diaphragm
Right triangular
Conn lateral part of post surface of right lobe to diaphragm
Coronary lig
Has sup and inf layers which encloses bare area of liver
What encloses lesser omentum?
Coronary lig
Fundus
Projects beyond inf border of liver
-surrounded by peritoneum, relation ant to ant abdom wall and post to transverse colon
Body
- sup surface has no peritoneum as it is attached to liver
- inf surface covered with peritoneum, related to transverse colon and duodenum
