RD 107 Lymph Node

Lymph Node

Transmission electron micrograph (TEM) of a small region of a medullary sinus of a lymph node. The lymphocytes in this region are tightly packed with occasional macrophages. Several processes of reticular cells are seen in cross section (cell bodies are not visible).

  • (green) -most abundant cell type that monitor for foreign substances
  • (tan) - phagocytic cells remove pathogens and debris
  • (orange) - network of reticular fibers that provide structural support

Subcellular Structures

  • Nucleus (blue) / Nuclear Envelope (purple)
  • Golgi Apparatus (yellow)
  • Mitochondria (red)
