Key: (1-3 are all part of the cortex)
- Zona glomerulosa
- Zona fasciculata
- Zona reticularis
Zona glomerulosa: Mineralcorticoids (E.g. Aldosterone – increases absorption of Na+ at the kidney (and thus water) at the expense of losing K+)
Zona fasciculata: Glucocorticoids (E.g. Cortisol – Released when under stress. Has anti-inflammatory properties, suppresses the immune system, increases blood sugar through gluconeogenesis, decreases bone formation, aids in metabolism of carbs, fats, and proteins)
Zona reticularis: Androgens (E.g. Estrogen – stimulates growth of pubic hair in females and Testosterone – stimulates growth of pubic hair in males)
Medulla: E.g. Epinephrine and Norepinephrine – enhances sympathetic responses.
