2023年5月1日 · The adrenal cortex takes part in steroidogenesis, producing glucocorticoids, mineralocorticoids, and androgen precursors. It has 3 distinct functional and histological zones: the zona glomerulosa (outermost layer), the zona fasciculata (middle layer), and the zona reticularis (innermost layer). [1] .

Cortisol, a critical glucocorticoid hormone produced by the adrenal glands, plays a pivotal role in various physiological processes. Its release is finely orchestrated by the suprachiasmatic nucleus, governing the circadian rhythm and activating the intricate hypothalamic–pituitary–adrenal (HPA) axis, a vital neuroendocrine system ...

The major secretions of the adrenal cortex (Box 4.2) are cortisol (the main member of the glucocorticoid family in humans), aldosterone (a mineralocorticoid), and the ‘weak’ androgens androstenedione and dehydroepiandrostenedione (DHEA).
