Blood-vessels of stomach and in- testines. Fig. 21.—Diagrammatic representation of the nerve-connections between the Stomach, Heart, and Blood-vessels. When the alcohol has entered the stomach, it stimulates nerve-fibres which are distributed over its inner surface. By some of these nerve-fibres impressions are carried to a cardio- accelerator centre at the base of the brain, and by others to vaso-motor centres either at the base of the brain or in the spinal cord. The cardio-accelerator and vaso-motor centres are in this way acted upon, and from them impressions are reflected to the heart, increasing its contractions, and to the stomach, dilating its blood-vessels, with the result that the
