Laryngeal receptors and their reflex responses

Abstract

The afferent activity originating from the larynx shows a considerable respiratory modulation. Receptors responding to pressure changes, inspiratory airflow (cold), and laryngeal movements have been identified. In addition, other receptors without a respiratory modulation are also described. Possible reflex effects of these receptors on breathing pattern, upper airway patency, and defense mechanisms in both adults and newborns are discussed.
