ANATOMY IX A NUTSHELL.

Stapedius, (b) chorda tympani arises a quarter of an inch above the stylo-mas- 

 toid foramen and passes upward and forward and enters the tympanum through 

 the iter chordae posterius on its posterior wall. This opening is between the 

 opening of the mastoid cells and the membrana tympanum. This nerve now 

 passes between the handle of the malleus and the vertical ramus of the incus to 

 the anterior inferior angle of the tympanum where it passes through the iter 

 chordae anterius (canal of Huguier) at the inner end of the Glasserian fissure.

While in the tympanum this nerve is covered with mucous membrane. It 

 now passes between the Pterygoid muscles and after receiving a t\vi<: from the 

 otic ganglion joins the lingual branch of the fifth nerve and passes with it to 

 the submaxillary ganglion. The sublingual gland may receive a few fillers 

 from this nerve, but most of them pass to the Inferior lingual muscle. Sonic 

 physiologists claim that the chorda tympani nerve supplies the anterior two- 

 thirds of the tongue with taste, others claim thai the ninth nerve passes with 

 this chorda tympani branch to be distributed to the anterior two-thirds of the 

 tongue, in such a case the ninth nerve is the nerve of taste for the entire tongue.
