Situated along the perimeter of the adrenal gland, the adrenal cortex mediates the stress response through the production of mineralocorticoids and glucocorticoids, including aldosterone and cortisol respectively. It is also a secondary site of androgen synthesis.

الطبقات
القشرة يمكن تقسيمها إلى ثلاث طبقات مميزة من الأنسجة بناء على تكوينهم.
الطبقة | الاسم | الناتج الرئيسي |
Most superficial cortical layer | zona glomerulosa | mineralocorticoids (eg, aldosterone) |
Middle cortical layer | zona fasciculata | glucocorticoids (eg, cortisol) |
Deepest cortical layer | zona reticularis | weak androgens (eg, dehydroepiandrosterone) |
خطوات تخليق الهرمون
- All adrenocortical hormones are synthesised from cholesterol.
Mnemonics
طبقات القشرة يمكن تذكـُّرهم عن طريق can be remembered with the mnemonic GFR: G - glomerulosa, F - fasciculata, R - reticularis.
Another mnemonic that is used is Go Find Rex, Make Good Sex: G - glomerulosa, F - fasciculata, R - reticularis, M - mineralcorticoids, G - glucocorticoids, S - sex hormones. (This mnemonic simplifies the relationship between the locations of production of glucocorticoids and sex hormones.)
Another mnemonic is "Salt, Sugar, Sex: The deeper you go, the sweeter it gets." As one moves layers into the adrenal cortex, compounds that control salt (mineralcorticoids), sugar (glucocorticoids), and sex (weak androgens) are produced.
