Oh,

sure.

So to get into sort of actual mechanism and phases of cough, you have inspiratory phase, compression of the vocal folds, expiratory phase that busts that apart and that causes your cough.

So your vocal folds are literally compressed.

slamming together every single time.

As far as actual pathway and cough reflex pathway, hypersensitive cough reflex, so specifically refractory chronic cough that I'm speaking of, has connections to both peripheral and central mechanisms.

So what I mean by that is peripheral mechanism being the actual changes in the airway sensory nerves.

Okay.
