Neuromuscular transmission in arterioles of guinea-pig submucosa

G D Hirst. J Physiol. 1977 Dec.

Abstract

1. Intracellular recordings were made from arterioles lying in the submucosa of guinea-pig small intestine. 2. Low frequency perivascular nerve stimulation evoked subthreshold excitatory junction potentials which facilitated. 3. Higher frequency stimulation caused summation of excitatory junction potentials and the initiation of muscle action potentials. 4. Arteriolar constriction was only observed following the initiation of a muscle action potential.
