(ba) Larger superficial petrosal nerve (N. petrosus superficialis 



major). 



(bb) Deep petrosal nerve (N. petrosus profundus) (0. T. great 



deep petrosal branch of carotid plexus). 



To display (&), cut away with bone-forceps the sphenoidal 

 process (processus sphenoidalis) of the palate bone and carefully 

 open the pterygoid or Vidian canal, which passes through the root 

 of the pterygoid process of the sphenoid bone.

Lateral branches of the olfactory nerves (after Hirschfeld). (From Poirier et Charpy, Traits 

 d'Anat. hum., Paris. 1899,, t. in., 3, p. 774, Fig. 417.) 



(c) Nasal rami (rami nasales). (Vide Fig. 132.) 



(ca) Lateral superior posterior nasal rami (rami nasales poste- 



riores superiores laterales). 



(cb) Medial superior posterior nasal rami (rami nasales poste-

(cba) Nasopalatine nerve of Scarpa (N. nasopalatinus 

 [Scarpae]). 



(cc) [Lateral] inferior posterior nasal rami (rami nasales poste- 



riores inferiores [laterales]). 



These have been previously examined in their peripheral dis- 

 tribution. 



(d) Palatine nerves (Nn. palatini). 



(da) Anterior palatine nerve (N. palatinus anterior). 



Trace it to its terminals in the tunica mucosa of the hard 

 palate.
