The physical presence of food in the upper GI tract is necessary; IV feeding won't terminate the MMC. Gastrin and CCK terminate the MMC in the stomach and the upper small intestine, not the ileum.
The physical presence of food in the upper GI tract, Gastrin, CCK, other hormones, and neural input are all involved in regulating the MMC. The MMC requires 80-120 min to travel from the antrum of the stomach to the ileum traveling 3-6 cm/min in the duodenum and 1-2 cm/min in the ileum.
