Role of Laryngeal Afferents in Cough

The superior laryngeal nerve (SLN) is the main source of laryngeal afferent activity. A clear respiratory modulation can be noted when recording from the peripheral cut end of this nerve in several mammalian species. This modulation is due to three types of sensory endings: cold, pressure and 'drive

The sensory neuropeptide, substance P (SP), is present in human airway nerves, beneath and within the epithelium where the condensed localization of neutral endopeptidase (NEP), the major enzyme degrading SP, is observed. To test the hypothesis whether SP stimulates the cough reflex and NEP modifies

While airway rapidly adapting receptors can mediate the cough reflex, much evidence suggests that bronchial C-fibre receptors are also involved in guinea-pigs and man. In man local and systemic C-fibre stimulants have a potent tussive action, which is blocked by low doses of local anaesthetics which
