Reflex excitation and inhibition of the lower oesophageal sphincter induced by gastric distension in the cat.


Reflex responses of the lower oesophageal sphincter (l.o.s.) to distension of the stomach were studied by electromyographic and manometric techniques. Distension of the fundus and gastric antrum by inflation of a balloon elicited two types of reflex response of the l.o.s. Thus, whereas excitatory responses were recorded following slight distensions, larger… (More)
