Anatomical Consideration 



Snout. — The snout is formed by a fusion of the upper lip and the 

 structure that corresponds to the nose in other animals. It is short 

 and cylindrical. The skin of the snout is thin and quite sensitive. 

 The nostrils are open on the flat surface of the snout. They are 

 round and rather small and separated by the os rostri which is a 

 prolongation of the septum nasi. 



Nasal Cavity. — The nasal cavity varies in different breeds of swine, 

 but in general it is long and narrow. It is divided behind a trans- 

 verse plate into an upper part that communicates with the meatus 

 of the ethmoid and a lower or respiratory portion. The nasolachrimal 

 duct is in the posterior portion of the ventral portion of the cavity.
