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

    beta cells produce insulinalpha cells produce glucagon

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

  • Diabetes Mellitusinsufficient production or use of insulinwithout insulin, blood sugar levels rise quickly after eating (hyperglycemia)

    because glucose is eliminated in urine, body uses protein & fat as energy source

  • Adrenal Glands(Image from: http://images.yourdictionary.com/adrenal-gland)adrenal medulla produces adrenaline and noradrenaline

    adrenal cortex produces 3 different types of hormones

  • Adrenal Cortexglucocorticoidsgroup of hormones designed to keep blood glucose levels high (in times of stress)mineralocorticoidsgroup of hormones that regulate salt-water balance (such as aldosterone)sex hormones

  • Reproductive Hormones

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

  • Puberty in Maleshypothalamus 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

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

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

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