Membrane potential and tension were recorded simultaneously from the smooth muscle of the rat tail artery. A single stimulus to the perivascular nerves caused a tension transient. The tension transient had two components, one due to a muscle action potential and one due to alpha-adrenoceptor activation. During trains of stimuli most of the tension was due to alpha-receptor activation, even when every stimulus caused a smooth muscle action potential.
