| Popis: | An ultrastructural study of the hepatopancreas of the terrestrial isopod, Armadillidium vulgare, indicates that morphological change in intercellular membrane apposition parallels functional differention of cells. In the isopod the midgut is structurally and functionally represented by the hepatopancreas. Each of the four lobes of this structure is histologically differentiated into regenerative, transitional and glandular regions, which progress from the distal to the proximal end respectively, and then connect through ducts to the hindgut.The distribution of cellular organelles is similar in all cells of the regenerative region. Plasma membranes of adjacent cells are separated by a distance of 160 A, (fig. 1). There is no indication of specialized membrane apposition such as junctional complexes or gap junctions. The cell membranes do not exhibit infoldings or extensive convolutions. |
