Question

Quizplus · Accepted Answer

Slow waves refer to cycles of depolarization and repolarization in the smooth muscle cells of the gastrointestinal tract. These waves set the basic rhythm of gastrointestinal contractions, but do not necessarily result in actual contractions. The contractions themselves are initiated by other factors such as hormones, neurotransmitters, and stretch receptors.
