Popis:	Visible light, as usually used for intravital microscopy, causes dilatation of the arterioles of the denervated frog submaxillary muscle. The minimal effective intensity of illumination of the object was 15 lx. The degree of dilatation of the arterioles in response to maximal intensity of light (250 lx) was inversely proportional to the initial diameter of the vessel. Arterioles 20–40 μ in diameter differed in their reactivity depending on the thickness of their walls. Highly reactive arterioles have thick walls. Their diameters were doubled or moreby illumination with visible light. Photic vasodilatation is reversible.
