قشرة الكظر
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.
