Note these features of the renal medulla, in contrast with the renal cortex.

  • No renal corpuscles are present.
  • All tubules are approximately parallel
    • In this specimen, most tubules are cut in cross section, indicating that they are arranged perpendicular to the plane of section.
    • Compare with a different plane of section.

The larger tubules in this image are collecting ducts.  The smaller tubules are loops of Henle.  Click on the thumbnail at left for higher magnification.
