    • Effects: Normal development and secretion of thyroid hormone
  10. ACTH
    • Organ: Hypothalamus
    • Target: Adrenal cortex - Zona fasciculata
    • Effects: Produce adrenal hormones: cortison, DHEA
  11. LH
    • Organ: Anterior Pituitary
    • Target: Gonads
    • Effects: 
    • Male: make testosterone
    • Female: ovulation, corpus luteum - make estrogen/progesterone
  12. FSH
    • Organ: Anterior Pituitary
    • Target: Gonads
    • Effects: Gamete production
  13. PRL
    • Organ: Anterior Pituitary
    • Target: Breasts - Mammary Glands
    • Effects: Milk production
  14. MSH
    • Organ: Anterior Pituitary
    • Target: Skin & brain
    • Effects: Produce melanin
  15. Oxytocin
    • Organ: Hypothalamus; Secreted by the Posterior Pituitary
    • Target: Uterus, brain, breasts, vas deferens, prostate
    • Effects: Uterine contractions, milk ejection, pair bonding, contract vas deferens and prostate during orgasm
  16. ADH
    • Organ: Hypothalamus; Secreted by Posterior Pituitary 
    • Target: Kidneys - distal convoluted tubules, collecting ducts; sweat glands
    • Effects: Prevents urine formation; reabsorb water
  17. T3 & T4
    • Organ: Thyroid
    • Target: Whole body except for spleen, testes, and uterus
    • Effects: Increase metabolism, maintain blood pressure, & body temperature, burn fat, use glucose
  18. Calcitonin
    • Organ: Thyroid 
    • Target: Bones - osteoclasts and osteoblasts
    • Effects: Lower blood calcium; build bone
  19. PTH
    • Organ: Parathyroid
    • Target: Bones and kidneys
    • Effects: Osteoclasts degrade bone; Kidneys reabsorb calcium and secrete phosphate
  20. Zona Glomerulosa: Mineralocorticoids (Aldosterone)
    • Organ: Adrenal Cortex
    • Target: Kidney - distal convoluted tubules
    • Effects: Regulate electrolytes; reabsorb sodium, excrete K; increase water retention; increase BP
  21. Zona Fasciculata: Glucocorticoids (Cortisol)
    • Organ: Adrenal Cortex
    • Target: Skeletal muscle, liver, adipose, blood vessels, and immune system
    • Effects: Degrade muscle protein to produce AA, gluconeogenesis, degrade fat, suppress immune system, vasoconstriction
  22. Zona Reticularis: Gonadocorticoids (Androgens, DHEA, Testosterone)
    • Organ: Adrenal Cortex
    • Target: Whole body
    • Effects: Start puberty, secondary characteristics, female sex drive
  23. Catecholamines: E and NE
    • Organ: Adrenal Medulla
    • Target: Heart, liver, arterioles, smooth muscle of reproductive system
    • Effects: Fight or flight - increase SNS response, increase HR, dilate vessels, increase glucose
  24. Alpha cells: Glucagon
    • Organ: Pancreas
    • Target: Liver
    • Effects: Break down glycogen, gluconeogenesis, raise blood (glucose)
  25. Beta cells: Insulin
    • Organ: Pancreas
    • Target: Liver, skeletal muscle, adipose
    • Effects: Lower blood (glucose), allow glucose into cells, synthesize glycogen
  26. Estrogen
    • Organ: Ovaries
    • Target: Genitals, skeleton, brain, reproductive system
    • Effects: Reproductive maturation, secondary sex characteristics, ovarian cycle
