EM 074 Interlobular Duct

Interlobular Duct

Transmission electron micrograph (TEM) of an interlobular duct in the pancreas.

Similar to the salivary glands, the exocrine pancreas has intercalated ducts, intralobular ducts, and interlobular ducts.

in the pancreas have a simple cuboidal epithelium. The individual cells are approximately the same width and height.

  • (dark green)
    • Desmosomes (macula adherens; ,; orange) - junctional complex specialized for cell-to-cell adhesion
  • (blue) / Nuclear Envelope (purple)
  • (yellow)
  • (red)
  • Endoplasmic Reticulum (cyan)
  • Cytoplasm (green)

The (purple) is seen as a thin, fuzzy line around the duct. It contains a network of reticular, collagen IV fibrils.
