By Matt Fowler. ABC has picked up Marvel's Agent Carter for a second season, while Agents of SHIELD will be back for Season 3. While Agents of SHIELD's pick up was more or less expected, the Agent Carter news comes as an awesome semi-surprise since its fate was more up in the air.
Where are the adrenal glands? The adrenal glands are small glands that sit on top of the kidneys in the retroperitoneum (i.e. the deepest part of the abdomen). They are several centimeters in length and each weighs 4-6 grams.
The indications for surgical removal of the adrenal gland are relatively straightforward and include, but are not limited to the following: 1  Tumors of the adrenal cortex which overproduce hormones. One such tumor is shown in the picture...it is the round yellow mass located within the triangular adrenal gland. This picture is blown up about 2-fold to make it easier to see. The normal adrenal gland is NOT this big. Endocrine glands are very important despite their small size since they make important hormones. Tumors of the adrenal medulla which overproduce adrenaline (pheochromocytoma). Most solid tumors of the adrenal gland which are greater than 4 cm (~2 inches) regardless of whether they produce hormone or not (to rule out malignancy).
