The adrenal glands sit atop the kidneys enclosed in a layer of fat.
Structure of the Glands.
-
The pyramid-shaped glands consist of an inner adrenal medulla and an outer adrenal cortex.

The adrenal medulla is made up of modified postganglionic neurons that are connected to the sympathetic nervous system.

The adrenal cortex makes up most of the adrenal glands and consists of epithelial cells in three layers--an outer, middle, and an inner zone.
