1. The Endocrine System

5. FOLLICLE STIMULATING HORMONE -FSH LUTEINIZING HORMONE- LH  Stimulates the production of gametes in ovaries and testes  Stimulates the release of gonadal hormones in males and females  Stimulates the ovulation of the egg and the formation of the corpus lutea in the follicle, which will release progesterone- the pregnancy hormone  Stimulates the Leydig cells in testes to release androgens, such as testosterone

9. Stimulates the thyroid to release its hormone: thyroxine Influences metabolic rate, growth, and development.

10. Calcitonin- causes calcium to be stored on bones (decreases calcium in blood) Parathormone- relases calcium stored on bones ( increases calcium in blood)

11. Glucocorticoids- cortisol- targets the Liver and other tissues to release Glucose. Mineralcorticoids-aldosterone- increases reabsorption of Na+ in kidneys and excretion of K+, controls volume of ICF and blood Stress! Adrenal Cortex Anterior Pituitary Negative feedback

13. Regulate synthesis of melanin in melanocytes in skin and hair, also linked to appetite and sexual arousal

14. (aka Vasopressin) Hormones made in the HYPOTHALAMUS but stored in the……

15. LOVE Positive Feedback

16. Stimulus- decreased blood pressure, increased osmotic concentration, dehydration Target/Response- Arterial walls/Vasoconstriction for increased pressure, Distal tubule of kidneys/reabsorption of water for increased blood volume and pressure.

18. Stress!

19.  aka Adrenaline  “Fight or Flight” response  Sudden response to fear, anger, pain, or physical exertion  Causes vasoconstriction  aka Noradrenaline  “Rest and Digest” response  Responsible for return to homeostasis  However, causes vasoconstriction, too

20. Antagonistic hormones that control blood glucose levels Beta cells Alpha cells

21. Enzymes affecting nearby tissues

24. Heat Memory Contraction / relaxation of muscles

25. Stimulates the development of T lymphocytes

26. Produces melatonin- Which communicates information on environmental lighting to other tissues in the body

29. Melatonin has important effects in integrating photoperiod and affecting circadian rhythms. It has significant effects on reproduction, sleep-wake cycles and other phenomena showing circadian rhythm.
