500 ORGANS OF DIGESTION. 



3. The Circumflexus, or Tensor Palati, is behind the pterygoid 

 process of the sphenoid bone. It arises from the spinous process 

 of the latter behind the foramen ovale, and from the contiguous 

 part of the Eustachian tube; it then passes downwards in con- 

 tact with the pterygoideus internus muscle, and terminates in a 

 broad tendon below, which winds around the hook of the inter- 

 nal pterygoid process, and is inserted into the soft palate near 

 its middle, and into the posterior lunated edge of the palate 

 bone. 



It spreads out or extends the palate. 



4. The Levator Palati is on the inner side of the last. It 

 arises from the point of the petrous bone, and from, the contigu- 

 ous part of the Eustachian tube, and passes downwards to be 

 inserted into the soft palate. This muscle, in the dissection of 

 the pharynx may be seen between its external edge, and the pte- 

 rygoideus internus muscle. 



It draws the soft palate upwards. 



5. The Azygos Uvulae is in the centre of the soft palate and 

 of the uvula. It arises from the posterior pointed termination of 

 the middle palate suture, and goes down into the uvula. 



It draws the uvula upwards, and diminishes the vertical 

 breadth of the soft palate. 



When the mucous membrane is removed, the upper constric- 

 tor of the pharynx appears between the anterior and the poste- 

 rior half arches.

OF THE GLANDS OF THE MOUTH. 



THESE glands consist in such as are muciparous, and in 

 such as are salivary. 



SECT. I. MUCIPAROUS GLANDS. 



These glands (GlandulcB Muciparce) are whitish, somewhat 

 oval and flattened, and are from the fraction of a line to two
