Adrenal Gland

Abstract:

The adrenal cortex is actually four separate glands, each with a principal product. The adrenal cortex produces steroid hormones from its three zones. The zona glomerulosa, the outermost zone, produces aldosterone primarily under angiotensin II stimulation. The zona fasciculata and zona reticularis are responsive to adrenocorticotropin, and their major products are cortisol and dehydroepiandrosterone sulfate, respectively. The adrenal medulla is an extension of the sympathetic nervous system, which produces catecholamines, primarily epinephrine. The adrenal cortex functions primarily to respond to environmental and physiologic stress, to restore homeostasis. The zona reticularis develops throughout childhood and then involutes with aging.
