Inhibition of the contractile activity of the stomach induced by psychogenic stress persisted after blockade of muscarinic and nicotinic cholinergic receptors and α2 and β1/β2-adrenergic receptors. Stress-induced increase in contractile activity in the proximal part of the duodenum persisted during blockade of muscarinic and nicotinic cholinergic receptors, β1/β2-adrenergic receptors. At the same time, blockade of the above cholinergic and adrenergic receptors eliminated the stress-induced increase in contractive activity in the distal part of the duodenum.
