Transmural stimulation applied to the atropinized human taenia coli caused relaxation which was resistant to adrenergic neuron blocking agents. This relaxation was, however, entirely abolished by tetrodotoxin. These results may suggest the presence of non-adrenergic inhibitory nerves in the human taenia coli.
