of the muscle must be dissected from behind, after removing the constrictors of 



the pharynx.) ... 



The palato-glossus (Fig. 1339) is a small bundle arising from near the midd 

 line of the oral side of the lower part of the soft palate, forming by its projection the 

 anterior pillar of the fauces, in which it runs to the tongue, where it joins the trans- 

 verse fibres. The pair of muscles act as a sphincter tending to close the passage from 

 the mouth to the pharynx. A thin expansion from this muscle passes over the tonsil. 



Vessels. The arteries of the palate (both hard and soft) come chiefly from 

 the descending palatine, which, emerging from the posterior palatine canal, runs for- 

 ward along the inner side of the base of the alveolar process. It sends a few branches

inward and backward to the front of the soft palate, which is supplied on the side by 

 a branch either from the facial or from the ascending pharyngeal. It is to be noted 

 that no vessel is likely to interfere with the division of the tensor palati at the inner 

 side <>f the hamular process. 



The -'fins of tin- hard palate follow in the main the arteries. Those of the upper 

 side of the soft palate join the plexus of the zygomatic fossa. The larger ones of the 

 under ^ide connect with the veins of the tonsil and the root of the tongue. 



The lyntphatii-* of the hard palate and of the under side of the soft palate form 

 a rich plexn-. Those on the upper side of the latter are small. The chief current is 

 to the deep glands of the neck.
