在犬小肠中发现了几种简单（S）和复杂（C）的推进和非推进活动模式，非推进活动由（1）静止的单个收缩（S）和（2）静止的收缩簇（C）组成。导致腔内容物反口推进的模式为（1）传播性收缩（S），（2）传播性功率收缩（S），（3）迁移性运动复合体的III相（C），以及（4）迁移性收缩簇（C）。推进电机模式的传播速度显着不同，他们增加了以下顺序：第三阶段，迁移集群收缩，传播功率收缩，传播收缩。管腔内容物的逆行运输由两种不同的活动产生：（1）逆行传播收缩（S）和（2）逆行功率收缩（S）。并伴有胃肠反流。
In the canine small intestine several simple (S) and complex (C) patterns of propulsive and nonpropulsive activities were found. The nonpropulsive activity consisted of (1) stationary individual contractions (S) and (2) stationary clusters of contractions (C). Patterns leading to aboral propulsion of luminal contents were (1) propagating contractions (S), (2) propagating power contractions (S), (3) phase III of the migrating motor complex (C), and (4) migrating clusters of contractions (C). The propagation velocities of the propulsive motor patterns differed markedly; they increased in the following order: phase III, migrating clustered contractions, propagating power contractions, propagating contractions. A retrograde transport of luminal contents was produced by two different activities: (1) retrograde propagating contractions (S) and (2) retrograde power contractions (S). They were accompanied with enterogastric reflux.
