  1. Hormones That Affect Blood Sugar & Reproductive Hormones 8.2 & 8.5

  3. Islets of Langerhans(Image from: http://health.howstuffworks.com/diseases-conditions/diabetes/diabetes1.htm) • groups of cells in the pancreas • beta cells produce insulin • alpha cells produce glucagon

  4. Regulation of Blood Sugar(Image from: http://tattoo12.co.gp/keyword/glucose%20levels)

  5. Diabetes Mellitus • insufficient production or use of insulin • without insulin, blood sugar levels rise quickly after eating (hyperglycemia) • because glucose is eliminated in urine, body uses protein & fat as energy source

  6. Adrenal Glands(Image from: http://images.yourdictionary.com/adrenal-gland) • adrenal medulla produces adrenaline and noradrenaline • adrenal cortex produces 3 different types of hormones

  7. Adrenal Cortex • glucocorticoids • group of hormones designed to keep blood glucose levels high (in times of stress) • mineralocorticoids • group of hormones that regulate salt-water balance (such as aldosterone) • sex hormones

  8. Reproductive Hormones

  9. Male Reproductive System(Image from: http://www.getceusnow.com/human_sexuality/penis.htm)

  10. Puberty in Males • hypothalamus releases gonadotropin-releasing hormone (GnRH) • activates the anterior pituitary to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH) • FSH acts on seminiferous tubules to increase sperm-production; LH acts on interstitial cells to produce testosterone

  11. Feedback in Males(Image from: http://www.medscape.com/viewarticle/721069_2)

  12. Female Reproductive System(Image from: http://www.webmd.com/infertility-and-reproduction/guide/female-reproductive-system-overview)

  13. Female Reproductive Cycle(Image on next slide from: http://all-nurses.blogspot.com/2011/05/menstrual-cycle.html) • hypothalamus releases GnRH • causes anterior pituitary to release FSH • FSH acts on ovaries and causes follicular development • follicle releases estrogen, which causes thickening of uterine wall and feeds back to inhibit FSH release
