  1. Adrenal Gland Cortex Lauren Kent Ashley Naveira Period 6 January 8, 2014

  2. Location Along the perimeter of the adrenal gland

  3. Hormones • Corticosteroid hormones: • Hydrocortisone: helps control the body’s use of fats, proteins, and carbohydrates • Corticosterone: Helps suppress inflammatory reactions in the body and affects the immune system • Aldosterone: regulates the level of sodium and potassium and helps maintain blood pressure • Androgenic steroids (androgen hormones) • Converted to female and male hormones, but are produced in larger amounts by the ovaries and testes.

  4. Homeostasis • Corticosteroid hormones: • Helps keep nutrients in balance and keeps the body healthy by regulating the immune system • Aldosterone • Prevents hypertension • Androgenic steroids (androgen hormones) • Controls the amount of reproductive hormones, to keep it in balance

  5. Feedback Mechanisms Adrenal cortex is regulated by negative feedback, involving the hypothalamus and adrenocorticotropic hormone.

  6. Releasing Hormones • Mineralocorticoids • Aldosterone • Increased absorption of sodium • Increased excretion of potassium and hydrogen ions • Produced in the adrenocortical zonaglomerulosa • Glucocorticoids • Cortisol • Stimulates release of amino acids from the body • Produced in response to stress • Produced in the zonafasciculata

  7. Release – Inhibiting Hormones • Aldosterone • When there is too much blood in the circulatory system, the heart produces atrial natriuretic factor, which inhibits the release of this hormone.

  8. Glandular Malfunction • Pheochromocytoma • Atumor that can form in the adrenal gland that is caused by producing too much adrenaline. • Congenital Adrenal Hyperplasia • Adisorder of the adrenal gland that prohibits it from producing enough cortisol • Addison’s Disease • Adisease in which the adrenal glands do not produce enough of many hormones

  9. Medical Procedures • Pheochromocytoma • Surgery to remove the gland or just the tumor or medication to stop the production of excess hormones • Congenital Adrenal Hyperplasia • Medication can be taken to replace the hormones that are not being produced • Addison’s Disease • Take oral medication to replace the hormones that the body lacks. Additional salt may need to be added to their diet as well
