Adrenal Gland Cortex

Location

Along the perimeter of the adrenal gland

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.

Homeostasis

Corticosteroid hormones: Helps keep nutrients in balance and keeps the body

healthy by regulating the immune systemAldosterone

Prevents hypertensionAndrogenic steroids (androgen hormones)

Controls the amount of reproductive hormones, to keep it in balance

Feedback Mechanisms

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

Releasing Hormones

Mineralocorticoids Aldosterone

Increased absorption of sodium Increased excretion of potassium and hydrogen ions

Produced in the adrenocortical zona glomerulosa

Glucocorticoids Cortisol

Stimulates release of amino acids from the body Produced in response to stress

Produced in the zona fasciculata

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.

Glandular Malfunction

Pheochromocytoma A tumor that can form in the adrenal gland that is

caused by producing too much adrenaline.

Congenital Adrenal Hyperplasia A disorder of the adrenal gland that prohibits it from

producing enough cortisol

Addison’s Disease A disease in which the adrenal glands do not produce

enough of many hormones

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
