“…Our results show some similarities to the experiences of Dunker et al (1972). These authors demonstrated a respiratory response to electrical stimuli of the nervi laryngici craniales only.…”

“…Otherwise, it has been demonstrated that respiration was diminished and slowed, when the stimuli to the nervi laryngici craniales were just above threshold, but accelerated on stronger stimulation. The respiration was never affected by stimulation of the nervi laryngici caudales (Porter, 1963;Dunker et al, 1972).…”

“…The nervi laryngici craniales and caudales are the only branches of the vagus nerve which contain somato-sensory fibres and vago-vagal reflexes evoked via these nerves help to coordinate laryngeal muscle activity during respiration and phonation. Their central innervation patterns are extremely complex (Dunker et al, 1972).…”

The role of upper airways and of sensoric receptors on reflex bronchoconstriction

The influence of bilateral transection of the nervi laryngici cranialis, laryngici caudalis and glossopharyngici on ACH and allergen-induced bronchoconstriction was tested in 15 dogs. In three dogs the free preparation of bilateral nervi laryngici cranialis was performed for control measurements. Partial transection of pulmonary left nervus vagus was performed in three dogs and compared to radical transection of the same nerve in three animals. Transection of the nervi laryngici cranialis as well as of the nervi glossopharyngici was followed by the inhibition of the allergen-induced bronchoconstriction. The bronchoconstriction following ACH challenge was not influenced by transection. Bronchoconstriction induced by allergen returned to the same values within three weeks after surgical intervention. Partial unilateral dissection of the vagus nerve on lung hilus shows a small decrease in bronchial constriction induced by allergen and by ACH. Complete unilateral dissection of the vagus nerve on the lung hilus reduced the bronchial constrictoric response to both substances significantly.

“…In experiments involving stimulation of the superior laryngeal nerve, it seems likely that there is a large number of affer ent fibers in the superior laryngeal nerve which originate from the mucosa of the upper larynx [Dunker et al, 1972], The prophylactic effect of transection of supe rior laryngeal nerve on antigen-induced bronchoconstriction originating in the upper respiratory tract makes it likely that this nerve is responsible for the sensoric innervation of the upper airtract [Zimmermann et al, 1984] and supports the hypo thesis that sensoric innervation and affer ent pathways, running through the nervus vagus are connected.…”

Influence of a Minimal Surgical Transection around the Trachea on Bronchoconstriction in Cats

The influence of a minimal surgical transection around the trachea on ACH- and allergen-induced bronchoconstriction was studied in a series of 21 cats. A significant smaller bronchoconstriction was observed after surgical transection around the trachea. The trachea isolation itself induced a smaller nonsignificant bronchoconstrictive response. This diminished response of the airways after this surgical intervention assumes an interruption of syncytial connections, which alters the response to bronchoconstricting stimuli of the whole bronchial system. The exact role of these syncytial connections has yet to be clarified
