postnasal
Throat-bound mucus path
Postnasal describes something located or occurring behind the nose, in the passage connecting the nasal cavity to the throat.
The word appears almost exclusively in postnasal drip—mucus that flows down the back of the throat rather than out the nostrils, often causing coughing or throat irritation.
