Q) Lymphatic drainage of Right adrenal gland is to 
a. Para aortic group
b. Inter Aortocaval
c. Pre aortic.
d. Para Caval

Answer free 

a)  Para-aortic lymph node.

Small lymphatic channels from both cortex and medulla drain into  the hilum, from where larger calibre lymphatic emerge to drain directly into the lateral group of  para-aortic lymph nodes

  • arterial supply is via three adrenal arteries 
    • superior adrenal artery (from inferior phrenic artery)
    • middle adrenal artery (from abdominal aorta)
    • inferior adrenal artery (from renal artery)
  • venous drainage 
    • adrenal veins emerge from the hilum and drain to different veins depending on the side:
      • left adrenal vein drains to the left renal vein
      • right adrenal gland drains to the IVC
