THE ARTICULATIONS AND LIGAMENTS. 



IN order to prepare the articulations, the student should select young, in 

 preference to subjects advanced in age, because in the former the density 

 of the cellular tissue is less than in the latter. As the ligaments are 

 prepared with difficulty when their external surface is dried up, care 

 should be taken to keep them protected from the air until the time to 

 dissect them, by covering them with wet linen rags, or with the hide of 

 the animal. 



It is convenient to separate the articulation which one wishes to study 

 by cutting the bones at a short distance from the articulatory surfaces. 

 The handling of the piece is thus more easy, and the dissection is made 

 under more favourable conditions. 



It is important to take as much care as possible of the muscles which 

 surround the articulations, so as to be able to study their connections 

 with the ligaments. If it is absolutely necessary to take away the 

 muscles, their attachments should be preserved. 



Study first the capsular ligaments, and then remove them so as to 

 display the funicular bands. The latter in their turn, are to be sacrificed 

 so as to expose, by means of different sections, the interosseous ligaments, 

 if any exist. Separate at last, in a complete manner, the two articular 

 surfaces, laying them bare, and then examine their conformation. 



The synovial membranes, with their different cul-de-sacs, being a very 

 important subject of study with reference to the diagnosis and treatment 

 of certain articular diseases, the student is recommended to preserve a
