MORPHOLOGY OF THE 



ventracl and to the left, to terminate in an apex. It has 

 three surfaces. The ventral surface is in relation with the 

 lesser omentum. The two lateral surfaces face somewhat 

 obliquely. The right surface looks ventrad and to the rigUt, 

 and upon it rests the pylorus. The left surface looks caudad 

 and to the left, and is in relation with the oesophagus, and 

 with the vertical arm of the lesser curvature of the stomach. 



The lesser curvature of the stomach forms an angle, 

 which for convenience may be described as being composed 

 of a vertical and of an oblique arm. 



Fig. 19 is a diagrammatic sketch of the stomach, showing 

 its approximate relation to the Spigelian lobe in the adult 

 and in the embryo cat. The interrupted line represents the

outline of this lobe in the adult, and the dotted Hne as it 

 appears at a certain stage of development in the embryo. 

 In the adult cat, the apex of the lobe rarely meets the point 

 of junction of the two arms of the lesser curvature, but 

 sometimes (as is shown in the figure) Hes close to it. 



The liver is a fixed organ, and it is important to bear 

 this in mind when considering the influence it exerts on the
