The flashcards below were created by user bradley.knox on FreezingBlue Flashcards. What would you like to do?


  1. What is the cortex of the adrenal gland derived from?
    Mesoderm
  2. What is the medulla of the adrenal gland derived from?
    neuroectoderm (neural crest cells)
  3. What is the shape of the right and left adrenal glands?
    • Right = small triangular
    • Left= larger semilunar
  4. What are the three zones of the adrenal cortex?
    • Glomerulosa
    • Fasciculata
    • Reticularis

    (Go Find Randy's adrenal cortex)
  5. What hormone is secreted by the glomerulosa layer of the adrenal cortex?
    Aldosterone

    (Globular minearals are salty)
  6. What hormone is secreted by the fasciculata layer of the adrenal cortex?
    Cortisol
  7. What hormones are secreted by the reticularis layer of the adrenal cortex?
    sex hormones (estrogen, progesterone, testosterone)
  8. What is the function of the glomerulosa layer of the adrenal cortex?
    regulate Na resorption which causes increases water retention and BP
  9. What controls the function of the glomerulosa later of the adrenal cortex?
    renin secreted from the juxtaglomerular apparatus of the kidney
  10. What part of the adrenal cortex increases lipolysis, glycogenesis, increased gluconeogenesis?
    Fascicuata layer (cortisol)
  11. What are estrogen, progesterone, and testosterone all derived from?
    androsteinone
  12. What does the adrenal medulla secrete?
    • nor-epinephrine
    • epinephrine
  13. What part of the nervous system does the adrenal medulla belong to?
    sympathetic nervous system
  14. What disease presents with increased perspiration, heart palpitation, paroxysms of hypertension, pressure headaches?
    pheochromocytoma
  15. What is the etiology of pheochromocytoma?
    • Caused by an adrenal medulla tumor
    • 10% bilateral
    • 10% malignant
    • 10% outside adrenal gland
    • 10% familial
  16. What disease presents with low BP, low Na, High k, high BUN?
    Addison's disease
  17. What disease is caused by an overfunction zona glomerulosa?
    Conn's disease
  18. What disease presents with high Na, high BP, water retention?
    Conn's disease
  19. What causes cushings syndrome?
    Excess cortisol production by the Zona fasciculata
  20. What produces ACTH and what part of the adrenal medulla is controlled by it?
    • Anterior pituitary gland
    • zona fasciulata production of cortisol
  21. What is the purpose of cortisol?
    increases blood glucose levels
  22. what is the effect of over production of ACTH?
    Increased production of melanocyte stimulating hormone
