AFTER the nerve has passed through the cribriform plate of the ethmoid bone, and 

 many of the branches have been distributed on the convoluted plates of this, they are 

 again concentrated a little lower down and coalesce with the lateral nasal nerve, and 

 then give off" branches to the Schneiderian membrane covering the turbinated bones 

 and the outer boundary of the nose, whilst others pass to the membrane covering the 

 septum. 



1. Bulb of the olfactory nerve. 



2. Superior nasal nerve of the first trunk of the fifth.
