  1. ´╗┐Hypothalamus Endocrine function?
    • Connects CNS to the endocrine system by stimulating the pituitary gland
    • Releases hormones that promote homeostasis
    • Controls Body temperature, Hunger, Thirst, Fatigue, Sleep, Circadian cycles.
  2. Pituitary gland - Posterior produces?
    • Antidiuretic Hormone (ADH)
    • Oxytocin
  3. Antidiuretic Hormone (ADH) made by, and does?
    • posterior Pituitary gland
    • aka vasopressin
    • Increases water reabsorption, which can counteract blood losses of up to 25%
  4. Oxytocin made by, and does?
    • posterior Pituitary gland
    • Uterine contractions
    • Lactation
  5. Pituitary gland - Anterior produces?
    • Regulates other endocrine glands
    • Target organs include: adrenal gland, mamillary glands, thyroid gland, gonads, and Releases growth hormone
    • Regulated by the hypothalamus and by negative feedback from these target organs
  6. Pineal gland location and Produces?
    • posterio of thalumus
    • Melatonin
    • Controls biological clock
  7. Thyroid location and Produces?
    • Neck
    • Affects rate of cell metabolism
    • controls how sensitive the body is to other hormones.
    • Lowers blood calcium levels
  8. Parathyroid location and Produces?
    • Neck
    • Increases blood calcium levels
  9. Thymus location and Produces?
    • Mediastinum
    • Produces thymosin - a secretion that promotes maturations of T-Cells
  10. Pancreas % distribution of cells?
    • 25% ╬▒ cells,
    • 60% ╬▓ cells,
    • 10% ╬┤ cells
  11. Pancreatic Alpha cells produce?
    • Glucagon: a hormone involved in Glycogenolysis & Gluconeogenesis
    • Glycogenolysis: glucose from Glycogen (a carbohydrate)
    • Gluconeogenesis: glucose from proteins and fats
  12. Glycogenolysis?
    • glucose from Glycogen (a carbohydrate)
    • Glycogen + Glucagon = Glucose
  13. Gluconeogenesis?
    • glucose from proteins and fats
    • Proteins & Fats + Glucagon = Glucose
  14. Pancreatic Beta cells produce?
    Insulin
  15. Pancreatic Delta cells produce?
    Somatostatin: Inhibits secretion of glucagon and insulin
  16. Adrenal glands Produce?
    • Epinephrine / Norepinephrine
    • Glucocorticoid hormones: ↑ blood glucose level, Inhibits inflammation, Salt & fluid balance
  17. Gonads - Ovaries produce?
    • Estrogen: Secondary sexual characteristics, & Egg development
    • Progesterone: Pregnancy related hormone
  18. Gonads - Testes Produce?
    Testosterone
