THE ORGANS OF DIGESTION 



The coronary ligament (ligamentum coronarium hepatis) (Figs. 1063 and 1066) 

 connects the posterior surface of the liver to the Diaphragm. It consists of two 

 layers. The upper layer is formed by the reflection of the peritoneum from 

 thp upper margin of the bare area of the liver to the under surface of the Diaphragm, 

 and is continuous with the right layer of the falciform ligament. The lower 

 layer is reflected from the lower margin of the bare area on to the right kidney 

 and suprarenal gland.

The lateral Ligaments (Figs. 1063 and 1066) are two in number, and are called 



the right and left lateral ligaments. 



The right lateral ligament (Ligamentum triangulare dextrum) (Figs. 1063 and 



1066) is in reality the right extremity of the coronary ligament. This ligament is 



triangular in form, runs from the liver to the Diaphragm, and is formed by the 



apposition of the upper and lower layers of the coronary ligament. 



The left lateral ligament (ligamen- 

 tum triangulare sinistrum) (Figs. 

 1063 and 1066) is a fold of some 

 considerable size, which connects 

 the posterior part of the upper sur- 

 face of the left lobe to the Dia- 

 phragm; its anterior layer is con- 

 iinuous with the left layer of the 

 falciform ligament. 



The round ligament (ligamentum 

 teres hepatis) (Figs. 1065 and 1067) 

 is a fibrous cord resulting from the 

 occlusion of the fetal umbilical vein. 

 It ascends from the umbilicus, in 

 the free margin of the falciform 

 ligament, to the notch in the ante- 

 rior border of the liver, from which 

 it may be traced along the umbilical 

 fissure on the inferior surface of the 



liver; on the posterior surface it is continued upward as the impervious ductus 



venosus (lig. venosum) as far as the inferior vena cava. 



Support and Movability of the Liver. The liver is movable within certain 



narrow limits. It moves with respiration. On inspiration it moves down with 



the Diaphragm to distinctly below the costal arch in the right midclavicular line. 



Its fixation to the under surface of the Diaphragm by means of connective tissue 



gives it its strongest support.
