The continuous but cyclic delivery of contents through the pylorus in the adult ruminant is regulated by the initiation of the migrating myoelectric complexes on the duodenal bulb. The motor responses of the pyloric antrum to the volume of digestive contents, the presence of lipids and ulcerogenic agents revealed that the inhibition of the motor antral activity, whatever its origin, resulted in a higher frequency of the duodenal cyclic motor events. Conversely, stimulation of duodenal motor activity, for example the increased frequency of migrating myoelectric complexes, resulted in the inhibition of the antral motor activity. It is suggested that the motor profile of the antroduodenal junction corresponded to interactions which fulfill the regulation of gastric emptying motor functions, with the first part of the duodenum as an extremely sensitive and rapid controlling mechanism.
成年反刍动物中，十二指肠球部移行性肌电复合波的启动调节着通过幽门持续但呈周期性的内容物输送。幽门窦对消化内容物体积、脂质和致溃疡因子的运动反应表明，无论其起源如何，胃窦运动活动的抑制都会导致十二指肠周期性运动事件的频率增加。相反，刺激十二指肠运动活动，例如增加移行性肌电复合波的频率，会导致胃窦运动活动受到抑制。有人提出，胃窦十二指肠连接处的运动模式对应着实现胃排空运动功能调节的相互作用，十二指肠的第一部分是一个极其敏感且快速的控制机制。
