1. The contractile activity of the cat urinary bladder was studied. Administration of adrenoceptor agonists and antagonists revealed that the responses of the smooth muscle are mediated by both pre-and post-synaptic α-adrenoceptor and by β2-adrenoceptor. 2. The evidence suggests that the cat urinary bladder possess muscarinic receptors and support the existence of a cholinergic link in noradrenaline transmission.
