===Vasculature===
The adrenal glands receive blood supply from the '''abdominal aorta''', '''renal artery''', '''cranial abdominal artery''' and '''caudal phrenic artery'''. Capillaries from these branch to form a '''capsular and medullary network'''. There is a '''central vein''', where venous blood pools, before flowing via satellite veins to join the '''caudal vena cava'''.
===Lymphatics===
The lymphatic network within the adrenal glands drains into the '''lumbar aortic lymph nodes'''.
===Innervation===
The parenchyma of the adrenal medulla is specialised for neurohormonal release, itself being a modified sympathetic ganglion. It is innervated by preganglionic fibres of the splanchnic nerve. The cortical cells are modified postganglionic neurones.
