  1. Hormones
    • Control Cellular resperation, growth and reproduction control body fluids
    • Control secretion of other hormones
    • Control behavior patterns
  2. Negative feedback loop
    • Thermostat turns furnace on when temp drops below certain points, turn off once reached
    • Hormones function similarly
  3. Hypothalamus
    • Controls secretion of the petuitary gland
    • Nerve cells produce chemical signals
    • Releasing hormones
    • Releasing inhibitory hormones
    • Controlled by¬†negative¬†feedback
  4. Anterior Pituitary Gland
    Produces growth hormone
  5. Growth Hormone
    • Cell metabolism and growth
    • too little is dwarfism
    • too much is gigantism
    • Controlled by releasing hormones from hypothalamus
  6. Thyroid stimulating hormone
    stimulates thyroid
  7. adrenocorticorpic hormone
    stimulates adrenal cortex
  8. melanocyte-stimulating hormone
    stimulates melanocytes
  9. Follicle-stimulating hormone
    • Females (stimulates ovarian follicle)
    • Male (Stimulates sperm production)
  10. Luteinizing hormone
    • Females (stimulates ovulation and progesterone production)
    • Males (Testosterone production)
  11. Lactogenic hormone
    Stimulates the milk production in women
  12. Posterior pituitary gland
    Produces ADH
  13. Antidiuretic hormone
    • Also called Vasopressin
    • Increased water absorbtion in kidney tubules
    • Deficiency results in diabetes insipidus
    • Regulated through osmoreceptors
  14. Oxytocin
    • Contraction of uterine smooth muscle
    • Constriction of mammary cell glands
    • Given after childbirth to constrict blood vessels to minimize risk of hemmorage
  15. Thyroid Glands
    Located below larynx on either side of the neck
  16. triiodothyronine
  17. Calcitonin
    Regulation of calcium and phosphate concentration
  18. parathyroid
    Located within the posterior thyroid gland secretes parathormone
  19. Parathormone
    Stimulates bone cell release of calcium and phosphate
  20. adrenal glands
    Located on top of each kidney in response to the sympathetic nervous system eponepherine/noreponephrine (from medulla)
  21. Pancreas
    • Populated by structures called the islets of Langerhaus
    • Beta cells (insulin)
    • Alpha Cells (glucogon)
    • Negative feedback
  22. hypoglycemia
    • low blood glucose
    • Confusion, clumsiness, coma, death
  23. hyperglycemia
    excess ketone production in the urine, dehydration, damage to brain, arteries, and kidneys
  24. diabetes mellitus
    Insufficient insulin production
  25. thymus gland
    • Located behind sternum
    • Secretes thymosin
    • Important for T-Cell production
    • Thymus shrinks as me age
  26. Pineal gland
    Located in the brain, near thalmus produces melatonin
  27. Melatonin
    • Inhibits reproductive functions
    • regulates body rhythm
  28. Serotonin
    • Neurotransmitter and vasconstrictor
    • stimulates smooth muscle constriction
  29. Ovaries
    Produces estrogen and progesterone
  30. Estrogen and Progesterone
    Development of female reproductive organs
  31. Testes
    Produces testosteron
  32. Testosterone
    Development of male reproducive organs
  33. Blood
