[The action of adrenergic substances on the smooth muscle of the rat trachea].
Adrenalin and noradrenaline first induced an increase in the trachea smooth muscle response with its subsequent decline in rats. Phentolamine decreases the muscle responses in its thoracic part and practically does not affect it in the cervical segments. The adrenergic neural fibres seem to terminate at the smooth muscle cells and the neurons of intramural ganglia.
