Endocrine System

  1. Anterior pituitary
    GH - growth hormone

    TSH - thyroid-stimulating hormone

    ACTH - adrenocorticotropic hormone

    PRL - prolactine

    FSH - follicle-stimulating hormone

    LH - luteinizing hormone
  2. Posterior Pituitary
    ADH  - antidiuretic hormone

  3. Thyroid
    T3 - thyroxine

    T4 - triiodothyronine

  4. Parathyroids
    PTH - parathyroid hormone
  5. Adrenal medulla

  6. Adrenal cortex
    Coritsol (95% glucocoricoids)

    Aldosterone (95% Mineralocoricoids)

    Sex hormones
  7. Panacreatic Islets
    Insulin (B-cells)

    Glucagon (A-cells)
  8. Testes
  9. Ovaries

  10. Thymus

    Promotes growth of T-cells active in immunity
  11. Pineal

    regulates mood, sexual development & daily cycles in response to the amount of light in the environment.
  12. Growth hormone - GH
    Anterior Pituitary

    Promotes growth of all body tissues
  13. Thyroid Stimulating Hormone - TSH
    Anterior Pituitary

    Stimulates thyroid gland to produce thyroid hormones
  14. Adrenocoticotropic - ACTH
    Anterior Pituitary

    Stimulates adrenal cortex to produce cortical hormones; aids in protecting body in stress situations (injury, pain)
  15. Prolactin - PRL
    Anterior Pituitary

    Stimulates milk secretion by mammary glands
  16. Follicle Stimulating Hormone - FSH
    Anterior Pituitary

    Stimulates growth & hormone activity of ovarian follicles and growth of testes: promotes development of sperm cells
  17. Luteinizing hormone - LH
    Anterior Pituitary

    Causes development of corpus luteum at site of ruptured ovarian follicle in female; sitmulates testosterone secretion in male.
  18. Antidiuretic Hormone - ADH
    Posterior Pituitary

    Also known as vasopressin

    Causes kidneys to conserve water by decreasing the amount of urine produces; at high concentration stimulates constriction of blood vessels causing increased blood pressure.
  19. Oxytocin
    Posterior Pituitary

    Uterine contractions; milk ejection from mammary glands
  20. Throxine - T4 and Triiodothyronine - T3

    • Growth & Development (physical & Mental)
    • Metabolism (increases rate)
    • Activity of the nervous system
  21. Parathyroid Hormone - PTH

    • increases calcium in the blood
    • regulates phosphorus in the blood.
  22. Epinephrine and norepinephrine
    Adrenal Medulla

    • Increases blood pressure & heart rate: activates cells influenced by sympathetic nervous system plus many not affeted by sympathetic nerves.
    • Liver releases glocuse for immediate energy
    • Fight or Flight
  23. Cortisol (Glucocorticoids)
    Adrenal cortex

    Aids in metabolism of carbohydrates, protiens and fats; active during stress. also exhibits antiinflammatory properties
  24. Aldosterone (Mineralocorticoid)
    Adrenal cortex

    • Aids in regulating electrolytes and water balance.
    • Decreases potassium & Increases sodium in the bloodstream. (Retentions of sodium causes retention of water and causes increase in blood pressure)
  25. Sex hormones
    Adrenal Cortex

    May influence secondary sexual characteristics
  26. Insulin
    Pancreatic islets, B-cells

    Transports glucose into cells; cellular metabolism of food especially glucose, decreases blood sugar.
  27. Glucagon
    Pancreatic islets A-cells

    Stimulates liver to release glucose into cells; increases blood sugar.
  28. Testerone

    Stimulates growth and development of testes and penis and secondary sexual characteristics (body and facial hair, voice change, stimulates maturation of sperm cells)
  29. Estrogen

    Stimulates growth of uterus and tubes and development of secondary sexual organs (breasts) changes in pelvis
  30. Progesterone

    Stimulates development of secretory tissue of mammary glands and uterine lining for implantation of fertilized ovum: aids in maintaining pregnancy.
  31. Thymosin

    Promotes growth of T-cells active for immunity
  32. Melatonin

    Regulages mood, sexual development, daily cycles in response to the amount of light in the environment.
  33. Tetany
    Spasms as a result of low calcium in the blood.
