Adrenal CortexThe firm, outer yellow layer of the adrenal gland which is derived from embryonic mesoderm and consists of 3 layers:
• Zona glomerulosa, the outermost layer, which secretes mineralocorticoids, primarily aldosterone
• Zona fasciculata, the middle layer, which secretes glucocorticoids, primarily cortisol, both at baseline levels and in bursts, when so commanded by ACTH from the anterior pituitary gland
• Zona reticularis, the innermost layer, which secretes androgens, primarily dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEA-S).
