(g) Pharyngeal bursa (bursa pharyngea}. 



Look into the nasal cavity behind and observe the septum of 

 the nose (septum nasi) separating the two choanae. The fol- 

 lowing are visible : 



(1) Nasopharyngeal meatus (meatus nasopharyngeus) . 



(2) Inferior meatus of nose (meatus nasi inferior). 



(3) Middle meatus of nose (meatus nasi medius). 



(4) Inferior turbinated bone (concha nasalis inferior). 



(5) Middle turbinated bone (concha nasalis media).

Medial aspect of right nasopharynx. (After Toldt, Anat. Atlas, Wien, 1900, 2 Aufl., p. 420, Fig. 686.) 



The posterior surface of the velum palatinum, the uvula, and 

 the arcus pharyngopalatinus are to be examined; they have 

 already been seen in front. Find the following : 

 (h) Pharyngo-epiglottic fold (plica pharyngo-epiglottica) . 

 (i) Aryepiglottic fold (plica aryepiglottica). 

 (j) Opening into larynx (aditus laryngis) (vide Fig. 95). 



Observe the epiglottis guarding the opening. 

 (k) Piriform recess (recessus piriformis) (0. T. sinus pyriformis). 



Foreign bodies often become lodged in this pocket. 

 (ka) Fold of laryngeal nerve (plica nervi laryngei). Look for 

 it in anterior part of recessus piriformis. 



Soft Palate (Palatum molle). (Vide Figs. 127 and 130.) 



The mucous membrane of this structure has already been 

 viewed from the mouth; it is now to be studied also from the 

 pharyngeal side.
