Functional Anatomy Of The Adrenal Gland

The human adrenal glands are paired, pyramid-shaped organs located on the upper poles of each kidney. The adrenal gland is actually a composite of two separate endocrine organs, one inside the other, each secreting separate hormones and each regulated by different mechanisms. The outer portion or cortex of the adrenal gland completely surrounds the inner portion or medulla and makes up most of the gland. During embryonic development, the cortex forms from mesoderm,- the medulla arises from neural ectoderm.
