232 ANATOMY OF THE RABBIT 



right posterior lobule. The latter lies close to the dorsal 

 body-wall, is separated from the anterior lobule by a rather 

 wide space which accommodates the pyloric end of the 

 stomach, and fits round the anterior end of the right kidney. 



(c) The gall bladder (vesica fellea) is an elongated, rather thin- 

 walled sac situated in a deep depression on the posterior 

 surface of the right anterior lobule. 



(d) The quadrate lobe (lobus quadratus) is a subdivision of the 

 right lobe lying medial to the gall bladder. Its lateral 

 limit is sometimes further indicated by a groove extending 

 ventrally from the depression containing the gall bladder. 

 It is frequently notched on its medial margin. 



(e) The caudate lobe (lobus caudatus ) is a small , well-separated , 

 lobe with an almost circular portion fitting against the base 

 of the left posterior lobule and an extension backwards 

 which is accommodated in the natural condition in the 

 space enclosed by the lesser curvature of the stomach. 

 Dorsally, it blends with the posterior right lobule and 

 passes over into the common dorsal mass wherein all the 

 main lobules of the liver meet. 



(/) The portal fissure (porta hepatis) is a large depression filled 

 by the portal vein at its point of entrance and containing 

 also the primary branches of the hepatic artery and 

 tributaries of the common bile duct. 



2. Trace the peritoneal connections as follows: 



(a) The lesser omentum, represented by the hepatoduodenal 

 ligament and the hepatogastric omentum, previously 

 divided. 



(b) The falciform ligament (lig. falciforme hepatis), a broad 

 median sheet connecting the anterior surface of the liver 

 with the diaphragm and extending backward to the ventral 

 abdominal wall. It is a remnant of a primitive ventral 

 mesentery. The position of this ligament indicates the 

 line of division of the liver into right and left lobes. The 

 free curved border of the ligament contains a thin cord, the 

 round ligament (lig. teres hepatis) , which marks the position
