240 HUMAN ANATOMY. 



The five lobes of the liver are: 



Right lobe, much the largest, is somewhat quadrilateral in 

 outline, and presents three fissures and two depressions, the latter 

 one for the right kidney and its suprarenal capsule, and the other 

 for the hepatic flexure of the colon. 



Left lobe, smaller, is separated from the right lobe by the 

 longitudinal fissure, and is in contact with the stomach. 



Lobulus quadratus, or square lobe, occupies the anterior 

 border of the under surface of the right lobe, between the um- 

 bilical fissure and the fissure for the gall-bladder, and in front 

 of the transverse fissure. 



Lobulus Spigelii occupies a similar position to the quadrate 

 lobe, along the posterior border, immediately back of it, from

which it is separated by the transverse fissure. It is bounded 

 laterally by the fissures for the ductus venosus and vena cava. 



Lobulus caudatus., or tailed lobe, unites the lobus Spigelii 

 with the right lobe, and separates the transverse fissure from 

 the fissure for the vena cava. 



The five ligaments of the liver are folds of peritoneum 

 except one, the round ligament, which is the remains of the 

 umbilical vein and ductus venosus of the foetus. 



They are: 



1. Longitudinal or falciform ligament consists of two layers 

 of peritoneum, attached by one margin to the under surface of 

 the diaphragm, and the sheath of the right rectus muscle, and 

 is attached to the liver along its anterior margin, from the notch 

 to its posterior border.
