Pathways for excitatory and inhibitory innervation to the guinea-pig tracheal smooth muscle
Experientia
|January 15, 1979
Abstract:
The trachea receives excitatory cholinergic innervation from the vagus nerve and the stellate ganglion. Inhibitory adrenergic fibres have the same sources. Those in the vagus nerve probably derive from high vagosympathetic anastomoses. Nonadrenergic inhibitory fibres have a preganglionic vagal supply.
