154: VISCERAL ANATOMY. 



Describe the 5 Ligaments of the Liver. Four are folds of peritoneum ; 

 one, the round ligament, is the obliterated umbilical vein and ductus venosus 

 of the foetus. The 



Suspensory or Falciform Ligament,! called also the Broad and the Lon- 

 gitudinal Ligament, is a sickle-shaped double fold reflected over the 

 round ligament, and is attached to the sheath of the right rectus muscle 

 as low as the umbilicus, and to the diaphragm. 



Coronary Ligament,ff is a double fold, containing firm areolar tissue in 

 its interspace, and extending from the posterior border of the liver to the 

 diaphragm. 



Lateral Ligaments, 2, are the triangular extremities of the coronary 

 ligament. 



Round Ligamentj ascends in the free margin of the suspensory ligament 

 from the umbilicus to the longitudinal fissure, in which it is continued to 

 the vena cava. 



Describe the 5 Hepatic Fissures. They are all situated on its under 

 surface, and separate the 5 lobes, one from another. They are the 



Longittidinal Fissurefi its anterior two-thirds, in front of the transverse 

 fissure, is called the Umbilical Fissure, from containing the umbilical 

 vein ; its posterior one-third is the Fissure of the Ductus Venosus, lodg- 

 ing the slender cord which represents that foetal vessel. 



Transverse Fissure, about 2 inches long, running from the longi- 

 tudinal towards the right ; and transmit the portal vein, hepatic artery, 

 bile-duct, lymphatics and nerves, surrounded by the Capsule of Glisson. 



Fissure of the Gall bladder? on the right of the longitudinal fissure, and 

 nearly parallel with it, extending from the anterior border, backwards to 

 near the right end of the transverse fissure. 



Fissure for the Vena Cava, extends inwards from the posterior border^ 

 where it joins the fissure for the ductus venosus; and gives exit to the 

 hepatic veins which here join the vena cava. This fissure is occasionally 

 a complete foramen. 



Describe the 5 Hepatic Lobes. Three are mere lobules, formed from 

 Ae right lobe by the smaller fissures. The 



Right Lobe," is much the largest, and presents the three small fissures 



and two depressions, one anteriorly for the colon, the other posteriorly 



for the kidney. 

 Left Lobe,t> is divided from the right by the longitudinal fissure, and rests 



upon the stomach. 

 I-obulus Quadratus,* in front of the transverse fissure, and between the 



umbilical fissure and that for the gall bladder.
