The adrenal cortex is the outermost layer of the adrenal gland. Within the cortex are three layers, called "zones". When viewed under a microscope each layer has a distinct appearance, and each has a different function. [13] The adrenal cortex is devoted to production of hormones, namely aldosterone, cortisol, and androgens. [14]
The zona reticularis (sometimes, reticulate zone) is the innermost layer of the adrenal cortex, lying deep to the zona fasciculata and superficial to the adrenal medulla. The cells are arranged cords that project in different directions giving a net-like appearance (L. reticulum - net). [1]
The zona glomerulosa (sometimes, glomerular zone) of the adrenal gland is the most superficial layer of the adrenal cortex, lying directly beneath the renal capsule. Its cells are ovoid and arranged in clusters or arches (glomus is Latin for "ball"). [citation needed] H & E staining of the adrenal cortex.
Steroid-producing adrenal tumours and hyperplasia of the zona fasciculata result in excess cortisol production and are the cause for adrenal Cushing's syndrome. [1] The genetic disorder McCune–Albright syndrome can also present as Cushing's syndrome in affected patients. Adrenal gland (zona fasciculata layer).
The adrenal cortex, situated along the perimeter of the adrenal gland; mediates the stress response through the production of various hormones The thymic cortex [ broken anchor ] , mainly composed of lymphocytes; functions as a site for somatic recombination of T cell receptors , and positive selection

The adrenal cortex originates from the thickening of the intermediate mesoderm. At five to six weeks of gestation, the mesonephros differentiates into a tissue known as the genital ridge. The genital ridge produces the steroidogenic cells for both the gonads and the adrenal cortex. The adrenal medulla is derived from ectodermal cells. Cells ...
