arises from the petrosal styloid process ; its tendon of insertion, 

 playing over the staphyline groove, expands and becomes lost 

 in the fibrous layer of the velum, of which it is a tensor and 

 depressor. 



LEVATOR PALATL 



(Peristaphjjjinus Internus.) 

 (¥iG. 90. h.) 



A slender muscle which arises with the last-named one, and 

 lies between it and the Eustachian tube. It passes directly to 

 the soft palate expanding between the Pharyngo-staphylinus and 

 the Palato-staphylinus, and finally joins its fellow of the opposite 

 side. It raises the velum

(Fig. 90. X:.) 



This is a broad, thin muscle, occuppng the inferior half of the 

 velum, and meeting its fellow in the median line ; they are 

 sometimes described as a single muscle. The fibres run back- 

 wards and outwards, and a portion, after following the free border 

 of the velum, is continued under the pharyngeal mucous mem-
