 The neck — Vertebrae — Cervical ligament. 



Next to the body of man, there is none of which the 

 anatomy has been more thoroughly worked out and more 

 minutely described than that of the horse. It is, in 

 fact, the one other animal body that is made the regular 

 subject of dissection by a whole profession of students, 

 and to which numerous special treatises are devoted. 

 Monographs on its structure, many of them copiously 

 and beautifully illustrated, abound in most languages
