GENERAL HISTOLOGY

Detailed explanation-1: -The porta hepatis provides attachment for the lesser omentum. It lies between caudate lobe posteriorly and quadrate lobe anteriorly.

Detailed explanation-2: -The caudate lobe lies between the fissure for the ligamentum venosum and the fossa for the inferior vena cava. The quadrate lobe is partly covered by the gallbladder in normal patients; anatomically, it lies between the fissure for the ligamentum teres and the gallbladder fossa.

Detailed explanation-3: -The ligamentum venosum (the obliterated ductus venosus) is attached to the inferior surface of the liver between the caudate lobe and the left lateral sector.

Detailed explanation-4: -The posterior surface of the liver is indented from top to bottom by this deep vertical groove, which ends down here at the hepatic notch. The lower part of the groove is formed by the ligamentum teres, which we’ve seen from in front.
