Abstract/OtherAbstract:
Observations by scanning electron microscopy indicate that the mucosa of the terminal part of the major pancreatic duct of the dog is organized into numerous, highly convoluted folds. The individual mucosal cells are tall, columnar and studded with numerous microvilli. These folds are highly vascularized. The intraluminal administration of bethanechol and norepinephrine is associated with subsequent increases and decreases of mean opening pressures. Mean opening pressures were not observed to be associated with autonomic nervous activity that was unaccompanied by changes in systemic arterial pressure. It is concluded that the terminal portion of the canine major pancreatic duct probably acts as a passive valve, the occlusive competence of which is influenced by the status of the vasculature of the lining mucosa in this region.
