|
|
Zona Glomerulosa Cells
|
Secretions stimulated by ACTH and Angiotensin II
Aldosterone - acts on DCT, Gastric Mucosa, Salivary and Sweat glands, reabsorption of Na (controlled by Renin-Angiotensinogen-Aldosterone System) Deoxycorticosterone (Mineralcorticoids) Found in the Adrenal Gland |
|
|
Zona Fasiculata Cells
|
Secretions stimulated by ACTH
Control metabolism of carbs, fats, and protein 1) Cortisol 2) Corticosterone 3) Small amounts of Gonadocorticoids (Glucocorticoids) - Controlled by CRH from hypothalamus In liver - these secretions induce gluconeogenesis and glycogenesis (ANABOLIC) In adipocytes - causes Lipolysis In muscle - causes Proteolysis (CATABOLIC) Secretions also inhibit macrophages and lymphocyte infiltration, induces atrophy of lymphatic system, and decreases circulating lymphocyte population. |

|
Zona Reticularis Cells
|
secretions stimulated by ACTH
1) DHEA (main) 2) Androstenedione 3) Weak Androgens (actions are usually insignificant) |
