ANATOMIC CONSIDERATION 

 Mouth 



The mouth in swine is relatively large due to the extension well 

 backward of the labial fissur£s. The upper lip blends imperceptibly 

 with the nose, forming the snout. The lower liiJ is short, closely 

 adherent to the maxillae and distiiictly pointed. The cheeks are 

 proportionally small because of the deeji labial fissures. The hard 

 palate is long and has a median groove, on each side of which are 

 about twenty ridges. 



The soft palate is thick, al)()ut 21/2 inches long and is nearly hori- 

 zontal. There may be a rudimentary median prolongation of the 

 soft palate. On either side of the oral surface there is a groove 

 and laterally there are raised areas — the tonsils which extend on 

 to the lateral walls and tongue. 



Tongue 



The tongue is long, relatively narrow and thin at the tip. The 

 mucous membrane lining the lips, clieeks and coA'ering the hard 

 palate is relatively smooth. 



Salivary Glands 



Parotid glands. — These glands are triangular in shape, located at 

 the base of the ear. The duct discharges opposite the upper fourth 

 or fifth molar.
