(gc) Inferior nasal concha (concha nasalis inferior) (0. T. infe- 

 rior turbinated bone). 



Is a highest nasal concha (concha nasalis suprema [San- 

 torini]) present? Observe the mucous membrane of the 

 nose (membrana mucosa nasi). Over the concha there is 

 much erectile tissue (plexus cavernosi concharum). What 

 is the spheno-ethmoidal recess (recessus spheno-ethmoid- 

 alis) ? 



The agger ("elevation") of the nose (agger nasi) (0. T. rudiment 

 of anterior turbinal).
