The Nasal Fossae Mucous Membrane, etc.: 

 Superior meatus. 

 Middle meatus. 

 Inferior meatus. 



Expose and trace the nerves and vessels ; first, those of the septum ; then remove the septum and 

 trace the nerves and vessels of the lateral walls. The cartilage of the septum should be exam- 

 ined and its connections noted before it is removed.

Supply septum, roof, outer wall, posterior ethmoidal cells. 

 Descending palatine: 



Branches to inferior meatus and lower turbinal bone. 

 Veins :

With the chisel carefully chip away the inner wall of the posterior palatine canal, and expose 

 Meckel's ganglion and the branches to and from it.
