A pair of very small arteries, n-, may be seen in the nasal chamber 

 between and parallel to the branches, n^; they lie close to each side 

 of the nasal septum and supply the anterior nasal region. They 

 apparently arise, as shown by the broken lines, from the loop of the 

 superior dental artery, dm^, though this could not be definitely 

 determined.
