  1. Adrenal Gland Medulla Erika Jones Alyssa Leslie 8B

  2. location • The adrenal gland medulla sits atop the kidney.

  3. hormones • Epinephrine (Adrenaline) • Norepinephrine (Noradrenaline) • Dopamine

  4. epinephrine • Fight-or-flight response • Regulates: • Heart rate • Blood vessel and air passage diameters • Metabolic shifts • Essential for maintaining cardiovascular homeostasis because of its ability to divert blood to tissues under stress.

  5. norepinephrine • Increases: • Heart contraction • Brains oxygen supply • Blood pressure • Sugar level of the blood • Causes vasoconstriction • Required for skeletal homeostasis

  6. dopamine • Chemical signal that sends information from one neuron to the next • “Feel good” chemical • Important for homeostasis because it keeps you from overworking and staying calm.

  7. feedback mechanisms

  8. what happens if the gland doesn’t function properly? • Hyper Adrenals (Overactive) • Can lead to Cushing’s Disease • Sugar Cravings • Muscle Spasms • Fatigue • Acid Reflux • High Blood Sugar • Headaches

  9. how to correct the problems of dysfunctioning adrenal medulla glands • Hyperactivity • Appropriate herbs & vitamins • Passion flower, hops, chamomile, fennel seeds, & vitamin C • Hypo activity • Herbs • Astragalus • Licorice root • Korean ginseng

  10. what happens if the gland doesn’t function properly? • Hypo Adrenals (Underactive) • Can lead to Addison’s Disease • Insomnia • Chronic fatigue • Salt cravings • Low blood pressure • Depression • Exhaustion • Colon Disorders

  11. Diseases • Pheochromocytoma • Rare, usually benign tumor that develops in the core of an adrenal gland. • Tuberculosis • Bacteria that can attack the spine, kidney & brain. • Addisons Disease • Occurs when your body produces insufficient amounts of certain hormones produced by your adrenal glands • Cushings Disease • Occurs when your body is exposed to high levels of the hormone cortisol • Autoimmune Disease • Occurs when the immune system mistakenly attacks and destroys healthy body tissue
