Abstract
Physiology of vascular smooth muscle which is probably devoid of adrenergic innervation and may lack cholinergic and histaminergic innervation has been studied by examination of 56 human umbilical arteries using an angioplethysmokymographic technic. Histamine uniformly caused vasoconstriction; 1-epinephrine, 1-norepinephrine and acetylcholine failed to cause significant reaction. Myoneural transmission of autonomic stimuli is discussed in terms of these results.Keywords
