The outer part of the adrenal gland is the adrenal cortex which makes three main hormones called steroids.
I have also had a Pheochromocytoma and had my left adrenal gland removed nearly two years ago.
The release of CRH triggers the pituitary gland's discharge of adrenocorticotropic hormone, which in turn stimulates the adrenal gland to secrete cortisol.
It is also the starting material from which steroid hormones are made by the adrenal gland.
The excess secretion of the hormone aldosterone into the blood is from an abnormal adrenal gland or glands.
