Mechanisms of Circulation Metabolism Coupling in Skeletal Muscle
Post-contraction vasodilation is unaffected by extrinsic denervation (3). It is therefore believed that local metabolites fully account for the phenomenon. Recently, however, neuronal cell bodies have been identified in the walls of arteries and arterioles (8). The experiments to be described indicate that these intrinsic nerves initiate post-contraction vasodilation. A unifying hypothesis is proposed which assigns specific functions to extrinsic sympathetic nerves, intrinsic nerves and metabolites in control of circulation during muscle contraction.
