DOMESTICATED ANIMALS. 



GENERAL CONSIDERATIONS. 



DEFINITION AND DIVISIONS OF ANATOMY. 



Anatomy is the science of organisation ; it studies the structure of 

 animated Kings when these have been deprived of life. It comprises two 

 grand divisions : physiological anatomy, which describes healthy organs, and 

 pathl< nj -Ii-iil nitiiti'iuy, whose object is the description of diseased organs. 



Physiological anatomy, in its turn, embraces : 



1. General anatomy, which is occupied with the analogous matters or 

 tissues of the animal body, with regard to their texture, and their physical, 

 chemical, and physiological properties, irrespective of the organs in which 

 these tissues exist. The particular study of the anatomical elements 

 nitcring into the composition of the tissues is named Iristulotjy. 



2. Descriptive anatomy, which studies the situation, form, and relation 

 of organs, as well as the relative arrangement of the various tissuc8 

 composing them, with the exception of the structure and properties of these 



:<'8. 



If this study bo devoted to a single species, it is designated special 

 niij. Example: human anatomy, or anthropotomy ; the anatomy of the 

 Horse, or hipputonnj. 



When descriptive anatomy embraces the study of the organisation of the 



entire animal kingdom, and examines the differences which characterise the 



same organ or the same series of organs in each class, family, genus, or 



'i-s, it is named comjHii-ufiri- nwtttunif. Restricted to the domesticated 



animals, this study constitutes veterinary anatomy.
