Abstract

The morphology of the exocrine secretory unit of the pancreas, i.e. the pancreatic acinus, is reviewed. The histological features of the acini and their relation with the duct system are described. The acinar three-dimensional architecture was studied by means of different ultrastructural techniques, some of which are complementary. The fine structure and morphodynamics of the acinar cells are also described. In addition, the location of the organelles in specific cytoplasmic domains and their close morphofunctional relationship with the sequential stages of secretion of the digestive enzymes are specially emphasized. Finally, morphological approaches are suggested to achieve a better comprehension of the physiological and pathological pancreatic activities whose morphodynamics need to be further elucidated or are almost totally unknown
