My  understanding is that it is erectile tissue in the nose which looks
after this - which allows the nasal mucosa to 'relax' after a period of
inhaling - the secretory cells to build up more secretions, mucous to be
removed etc.

(just looked up junquiera histology - calls them swell bodies, in the
concha, act every 20-30 minutes)

you would therefore need to look at the autonomic innervation/connections.
