Tuber Omentale
Papillary Process
Caudate Process
Peritoneal Attachments –
o Liver is enclosed in peritoneum (Ventral mesogastrium), except at the bare area
Ventral part
i. Falciform lig. – Attached to liver & anterior abdominal wall
o Inferior margin – Ligamentum teres hepatis (Remnant of L. Umbilical V.)
ii. Right & left triangular ligaments
iii. Coronary ligament – Superior & Inferior layers
Dorsal part
Lesser omentum – arise from inverted ‘L’ attachment
o Vertical limb – Ligamentum venosum (Remnant of Ductus
Venosus) o Horizontal limb - margins of porta hepatis
Lobes – Right & Left
Anatomical Division
Divided into Left and larger Right lobes :
Diaphragmatic surface – Falciform ligament
Visceral surface – ‘H’ shaped arrangement

, Right Lobe
Caudate lobe
-Between groove for IVC & Fissure for Ligamentum venosum
-Caudate process – Inferior to the right, connecting to the right lobe
- Papillary process – Inferior to the left
Quadrate lobe
-Between GB fossa & Fissure for Ligamentum Teres
Porta hepatis
-Arrangement
Portal Vein – posteriorly
Bile duct – anteriorly to the right
Hepatic artery – anteriorly to the left
o Left Lobe
Tuber Omentale (omental tuberosity) – near the
fissure for Ligamentum
venosum, right to gastric
impression
Functional Division
According to distribution of Bile duct, Hepatic artery, Portal vein. Oblique plane through the GB
Fossa & IVC groove divides it into left and right halves.
8 lobes
Caudate lobe is supplied by both hepatic arteries, both portal veins, both hepatic
ducts, but it has an independent venous drainage
Stability – Ligaments, Hepatic veins, Abdominal muscle tone
