  • Revised scale trauma

  • Reticular tissue

    A type of connective tissue consisting of delicate fibers forming interlacing networks. Fibers stain selectively with silver stains and are called argyrophil fibers. Reticular tissue supports blood cells in lymph nodes, bone marrow, and the spleen.
