The Suprarenal Glands



Position

  • They lie on each side of the vertebral column, against the superomedial surface of the corresponding kidney.

  • They are enclosed with the kidney, within the renal fascia.

  • A little fat separates it from the superior pole of the kidney.

Blood supply  

3 arteries

  • Superior suprarenal from the inferior phrenic
  • Middle suprarenal from the aorta
  • Inferior suprarenal from the renal artery

1 large central vein

  • the right - inferior vena cava
  • the left - left renal vein
   

Innervation

Autonomic from the coeliac plexus – medulla

Cortex has no nerve supply.

   

Lymphatics

Aortic lymph nodes

A tumor of the suprarenal medulla called pheochromocytoma is usually associated with a very rich blood supply. Abdominal aortography is frequently employed as a diagnostic procedure.
