Adrenal Blood Supply

There are three adrenal arteries – the superior that arises from the inferior phrenic artery, the middle that arises directly off the aorta and the inferior that arises from the renal artery usually as a branch of the capsular artery. This schematic only shows 3 branches per vessel, but in reality there is extensive branching before each artery actually enters the gland.
