[Mediators of the local reflex arc in airways of the rat and guinea pig].
Transmission of neural pulses from afferents to functional module's neurons in rats and guinea pigs can be carried out with the aid of the P substance. Further transmission to a smooth muscle of the trachea occurs through a neuro-muscular junction with acetylcholine as a transmitter. Transmission of inhibitory influences from the tracheo-bronchial receptors to the smooth muscle is carried out via nicotinic cholinoreceptors. Adrenergic mechanisms can modulate neural transmission at the level of intramural ganglia.
