REFLEX PATHWAYS CONCERNED IN INHIBITION OF HUNGER CONTRACTIONS BY INTESTINAL DISTENTION

Abstract

Hunger contractions were recorded in dogs by the balloon method before and after distention of Thiry jejunal loops. Distention of a loop by pressures of 70-130 mm. Hg inhibits gastric tonus and motility. By successive surgical sections of the vagi, splanchnics and sympathetic chains it was demonstrated that the reflex gastric inhibition could be mediated either by the vagi or splanchnics. Each set of nerves contained both afferent and efferent fibers. The evidence indicates that inhibition is more easily induced over the vagal pathways.
