Adrenal gland
The adrenal gland is a triangular-shaped organ situated at the superior pole of each kidney. Each gland is composed of two subdivisions having separate embryological origins: an outer cortex, the major source of steroid hormones, and an inner medulla, releasing catecholamines. A dense connective tissue capsule surrounds the organ. 5x, 40x
