Abstract

Although electrical and mechanical activities of the colon have been extensively studied in recent years, the relationships between them as well as their characteristics still remain to be adequately defined (1–9). This study was undertaken to determine the patterns of electrical and mechanical activities occurring in longitudinal and circular muscle layers of the canine colon. Distinctive and different electrical and mechanical activity patterns were observed in the two muscle layers.
