Fecal Propulsion (IMAGE)
Caption
This is an image of smooth muscle electrical activity recorded during fecal pellet propulsion along the isolated mouse colon. Isolated whole colon is shown from a video recording made above the colon. The fecal pellet inserted into the proximal colon propagates anally. As the fecal pellet passes over the first electrode a discharge of compound action potentials occurs in bursts at ~2 Hz. As the pellet passes over the second electrode a similar burst of 2 Hz muscle action potentials occurs behind the fecal pellet causing contraction of the muscle that underlies propulsion.
