Multiple neural circuits mediating airway sensations: Recent advances in the neurobiology of the urge-to-cough

•Airway sensory neurons have different embryological origins.•Vagal neurons originate from both the neural crest and epibranchial placodes.•Jugular vagal neural circuits resemble the somatosensory nervous system.•Nodose neural circuits resemble the viscerosensory nervous system.•This heterogeneity results in fundamentally different sensory biology.
