286 ANATOMICAL TECHNOLOGY. 



1-2 cm. square. Rinse the mucous surface with water or normal salt solution. The 

 structure will appear like that of the small intestine except that villi are absent. 



Microscopic Structure of the Intestinum amplum. (A) Peritoneal or serous coat. (B) 

 Muscular (unstriped) coat : (1) Longitudfhal layer ; (2) circular layer. (C) Submuco&a, 

 loose connective tissue coat. (D) Muscularis mucosae, unstriped muscular fibers arranged 

 both longitudinally and transversely. (E) Mucous coat, containing crypts of Lieberkuhn 

 and Fever's glands. 



The large intestine of the cat is completely invested by peritoneum, and is supported 

 by a dupiicature of the same ; hence in these respects it differs somewhat from man. See 

 Strieker, A, 391 ; Quain, A, II, 371. 



744. Hepar, az. Liver (Fig. 77, 713). Grasp the liver with the 

 hand and draw it in various directions. It is deeply divided (lobed) 

 and is supported in various parts by folds of peritoneum, the so 

 called ligaments of the liver. 



Lob I liepaticL The lobes of the feline liver have not been satis- 

 factorily homologized with those of the human liver, and the nomen- 

 clature is somewhat unsettled. (Owen, A, III, 485 ; Flower, 41). 

 For convenience, the following provisional names may be used : 



(A) Lobus sinister. Tins part of the liver is at the left of the 

 suspensory ligament (the ligament parallel with the meson and serv- 

 ing to hold the liver against the diaphragm). This lobe is deeply 

 divided, and its caudal or thin edge is on the ventral side of the 

 pyloric region of the stomach (Fig. 79). 



(B) Lobus cysticus Cystic lobe. This is at the right of the sus- 

 pensory ligament, and occupies the right ventral part of the abdo- 

 men. It contains the cholecyst or gall bladder, and hence cannot 

 be mistaken. It is in some cases deeply divided, and in others only 

 slightly. 



(C) Lobus dexter Right lobe. This is dorsad of the cystic lobe. 

 It is usually deeply subdivided, and is in contact with the ventral 

 aspect of the right kidney. 



(D) Lobus Spigelii. This is the smallest of the lobes of the liver. 

 It is dorsad of the left lobe and dextro-cephalad of the lesser curva- 

 ture of the stomach. It usually appears at the mouth of the fora- 

 men of Win slow, and may be fully exposed by tearing away the 

 peritoneum ( 728) at the lesser curvature of the stomach. 



745. CholecystisGrall bladder. This is a receptacle for bile, 

 and as stated above is partly imbedded in the cystic lobe. It is a 

 pear-shaped sac, and the larger end usually appears on the ventral 

 surface of the cystic lobe (Fig. 77). To expose it fully, turn the free 

 edge of the cystic lobe cephalad.
