title: Diversity of rhythmicity in gastrointestinal smooth muscles.
abstract: Diversity in smooth muscles is well shown by differences in gastrointestinal rhythms. Basic rhythmic activity apparently occurs only when there is interaction between clusters of cells. It is postulated that the oscillations of basic electrical rhythms result from action of a membrane ionic network. In addition to slow waves, gastrointestinal muscle is capable of acetylcholine-induced rhythms, of spontaneous "slow spikes" that may be similar to the Ca2+ component in stomach, of neurally paced migrating complexes, of Ca-EGTA plateaus and of stretch induced rhythms.
