Pacemakers in extrahepatic biliary ducts.
Pacemaker cells in the biliary system were studied by using electromyographic and histological methods. The pacemaker cells of the duodenal-biliary complex are located in the bile duct (predominantly, in its proximal part). They are characterized with enhanced spontaneous spike and slow-wave electrical activity. The pacemaker cells organize the sequential motor activity of the proximal and distal portions of ductus choledochus, with subsequent involvement of the duodenum into this activity.
