Summary Recent work on the physiology of gastrointestinal smooth muscle has been reviewed, it is concluded that:–1 The smooth muscle of the bowel wall is probably co‐ordinated by a slowly spreading electrical wave, which spreads from cell to cell. 2 The nerve plexuses in the bowel wall are not intimately related to the co‐ordination of the gut musculature in the small intestine. 3 The co‐ordination of the smooth muscle is disturbed by an anastomosis, and may be damaged for months, at Jeast, by the injudicious use of bowel clamps. 4 The different electropotential waves which may be recorded from the small intestine have been reviewed. 5 The mechanism of gastric emptying, and the possible methods of adaptation available to the gut following gastrectomy, are outlined. 6 The manner in which post‐gastrectomy dumping syndromes may be either initiated, or augmented, by vasomotor reflexes initiated from hyperactive bowel wall has been discussed. 7 The different mechanical characteristics of different parts of the small intestine have been discussed in connection with the use of small intestine transplants in urology.
