SYSTEMATIC SYNTHESIS OF TISSUES INTO ORGANS. 345 



1031. Remark. The tonsils are very apt to swell and be trouble- 

 some, being sore to the touch externally, and partially closing the pass- 

 ages within. In the latter case, if the trouble becomes permanent, a 

 portion of them can be removed by a very simple operation. 



1032. THE MUCOUS GLANDS OK FOLLICLES of the 

 mouth are very numerous, and scattered throughout its 

 lining ; they are also clustered as described abdve. 



1033. THE VEIL OF THE PALATE, or soft palate, is an 

 extension from the hard palate, constructed mostly -of 

 muscles, lined below and above, or before and behind, 

 by the lining of the mouth and nose, and in the centre 

 exhibiting a dependent point, called the uvula. 



1034. THE USE OF THE SOFT PALATE is to close the 

 communication between the upper and the middle part 

 of the pharynx, or between the mouth and the pharynx. 



Pharynx. 



1035. Remark. The pharynx has already been described. fl[ 961.) 



(Esophagus. 



1036. THE (ESOPHAGUS is merely a distensible, con- 

 tractile tube, extending from the pharynx downward in 

 front of the spinal column nearly, to the diaphragm, 

 when it turns slightly forward and to the left through 

 the cesophageal opening in the diaphragm (13, Fig. 181), 

 and connects with the stomach. (See Fig. TO.) 



1037. THE CESOPHAGUS is CONSTRUCTED of annular 

 and longitudinal muscular fasciculi (see Fig. 79), and 

 lined with an extension of the mucous membrane of the 

 pharynx and stomach. 



1038. Remark. The muscular rings at the lower part of the oeso- 

 phagus are somewhat stronger than those above. 



1039. THE USE OF THE (ESOPHAGUS is to receive food 

 from the pharynx and force it into the stomach. For
