  1. Melatonin funciton and location
    • Pineal Gland 
    • its function is to regulate  Circadian Rythm (sleep)
  2. Antidiuretic Hormone ADH location and function
    • Located in Posterior Pituitary Gland 
    • Function is to enhance water re-absorption for kidney to maintain stable blood pressure
  3. Oxytocin function and location
    • Located in Posterior Pituitary 
    • Its function is milk ejection
  4. T4 Thyroxine location and function
    • located in Thyroid Gland 
    • Function is to regulate metabolism
  5. T3 Triiodothyronine location and function
    • located in Thyroid gland 
    • its function is to regulate metabolism
  6. Calcitonin location and function
    • Located in Thyroid gland 
    • its function is to reduce blood calcium levels 
    • enhance calcium deposition in bones and decrease calcium re-absorption in kidney
  7. Parathyroid hormone PTH
    • Located in Parathyroid gland 
    • Increase Blood calcium level 
    • increase bone breakdown 
    • decrease calcium excretion from kidney 
    • increase abosrption by enhancing Vitamin D3 synthesis
  8. Aldosterone (Mineralocorticoids) location and function
    • Located in Adrenal Glands 
    • ↑Blood pressure by ↑ Na+ reabsorption in kidney ↓ K+ levels
  9. Cortisol (Glucocorticoids)/stress hormone location and function
    • located in Adrenal Glands 
    • regulates the bodies response to stress
  10. Sex hormone (androgens) location and function
    • located in Adrenal glands 
    • regulates reproductive functions
  11. Epinephrine (adrenaline, peptide) location and function
    • Located in Inner layer of Medulla 
    • Fight or flight response
  12. Difference between Primary and Secondary endocrine systems
    • Primary endocrine organ:Primary job is to secret hormone–e.g Hypothalamus, pituitary glands, parathyroid glands
    • Secondary Endocrine organ:Secreting hormone is not its major function–e.g Heart, Stomach, Liver
  13. Describe Anterior Pituitary gland
    • produces own hormone
    • thyroid stimulating hormone TSH
    • Adrenocorticotrophic hormone ACTH
    • NO neural connection w/ hypothalamus
  14. Describe Posterior Pituitary gland
    • Hormone storage only 
    • Neural connention w/ hypothalamus 
    • Antidiuretic hormone ADH 
    • oxytocin
  15. What are the 3 hormones secreted by Thyroid gland?
    • T3 triiodothyronine 
    • T4 Thyroxine 
    • Cacitonin
  16. What are the 3 hormones secreted by the Adrenal Glands?
    • Aldesterone 
    • Cortisol 
    • Sex hormone
  17. Pancreas secretes
    Endocrine and Exocrine
  18. Define Exocrine
    Enzymes and secretion for digestion
  19. Define Endocrine
    • Hormone secretion
    • α cell: Glucagon ↑ blood glucose
    • β cell: Insulin ↓ blood glucose
  20. What is Hyposecretion?
    • Too little secretion of hormones 
    • ex: type 1 diabetes
  21. What is Hypersecretion?
    • Too much secretion of hormone 
    • ex: too much hormone gigantism acromegaly
  22. How does the body regulate blood glucose level?

  23. What is Abnormal tissue responsiveness?
    • Normal hormone levels
    • Tissue responds inappropriately
    • E.g Type 2 diabetes
  24. Difference between primary and secondary secretion disorders
    • Primary: Abnormality in the endocrine organ that secrets the hormone
    • Secondary:Abnormality in hypothalamus or anterior pituitary
  25. High CRH + High ACTH + High Cortisol =
    Secondary Hypersecretion in hypothalamus
  26. Low CRH + High ACTH + High Cortisol =
    Secondary Hypersecretion in Anterior Pituitary
  27. Low CRH + Low ACTH + High Cortisol =
    Primary Hypersecretion in Adrenal cortex
  28. High CRH + High ACTH + Low Cortisol =
    Primary Hyposecretion in Adrenal Cortex
  29. What are 3 ways of hormone interaction?
    • Antagonism: (Antagonistic) Hormones oppose each other-Glucagon: ↑ Blood Glucose  -Insulin: ↓Blood Glucose
    • Synergism: (Synergistic) Net effect exceeds the sum of individual effects (1+1 = 5)
    • Permissiveness: (Permissive)    Presence of one hormone is needed for another hormone to exert its actions
