CHAPTER III 



THE LIMB IN SECTION 



A TRANSVERSE section is made across the stifle joint and the principal 

 nerves and vessels, ligaments, etc., are represented in Plate VII. 



The anterior tuberosity of the tibia has been sawn through and the 

 joint then disarticulated below the fibro-cartilaginous discs, so that the 

 superior surfaces of the two articular tuberosities of the tibia are repre- 

 sented. This surface of the internal tuberosity is seen to be continued 

 upwards on the inner aspect of the tibial spine. 



On the outer aspect of the spine is seen the attachment of the anterior 

 or external crucial ligament, in front of which the anterior coronary 

 ligament from the internal disc is observed to be inserted. 



Projecting outwardly from the postero-external angle of the internal 

 tuberosity, and placed just below its articular surface, is a well-defined 

 tubercle. This is the special tubercle to which the posterior crucial 

 ligament of the joint is attached inferiorly. The ligament is plainly 

 visible in the Plate. 



On the inner aspect of the joint the internal lateral ligament of the 

 stifle will be observed to be attached to the internal tibial tuberosity, the 

 attachment being just below the articular surface. 



Placed anteriorly in the Plate, three ligaments will be observed. 

 These are the external, middle, and internal straight ligaments of the 

 patella. The external ligament is attached to the outer or more prominent 

 division of the anterior tuberosity. The upper end of this portion is visible 

 since the saw has passed through it. The middle ligament is inserted
