[|Human|] Hi, i was just wondering during an asthmatic attack when there is narrowing of the airways, do the sensory fibres of the vagus nerve become stimulated leading to a parasympathetic reflex causing further bronchoconstriction? if thats not the case at all could you be able to explain the involvement of the vagus nerve in relation to an asthma attack?
[|AI|]  Reclothe tracheobronchial tree and the esophagus share common embryonic origins & autonomic innervation through VAGUS NERVE. The parasympathetic nervous system has also been implicated in asthma. Increased legal tone (mostly in the night i.e. nocturnal asthma) during sleep could promote bronchoconstriction. There is a diurnal variation in legal activity that has been demonstrated in asthmatic patients, with higher legal activities occurring in the night. So when vagus nerve stimulated it lead to parasympathetic reflex and triggers asthmatic attack typically in the night due to more bronchoconstriction. This is a very complex scientific proved study. Hope this will help you.
