The adrenal gland is divided into an outter cortex and an inner medulla. I look for the differentiation of these two regions. In addition, the zona fasiculata (the middle layer of the cortex) is characterized by cells that have a columnar arrangement (as indicated by the faint black lines in the photo above). When I see those cells, I know this is the adrenal gland.
