Simplified schematic pathway of the cough arc

Simplified schematic pathway of the cough arc
Stimuli that trigger cough can be broadly divided into mechanical, inflammation and infection, and chemical categories. Examples of each of these are listed in the box. These triggers stimulate the various airway receptors, all of which are vagal airway afferents. The triggers can also sensitize and alter the receptor phenotype. All signals end at the nucleus tractus solitaries, from which second order neurons project into the brainstem respiratory network, which is also responsible for regulating respiration. The cerebral cortex and subcortex can modulate these networks that have plasticity. Neurons from the brainstem network project onto the larynx and spinal motor neurons (respiratory muscles and sphincter) that are activated during cough.[1-4]
