groups of cells in the pancreas
beta cells produce insulin
alpha cells produce glucagon

4. Regulation of Blood Sugar (Image from: http://tattoo12. co

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
adrenal medulla produces adrenaline and noradrenaline
adrenal cortex produces 3 different types of hormones

7. Adrenal Cortex glucocorticoids mineralocorticoids sex hormones
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

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

13. Female Reproductive Cycle (Image on next slide from: http://all-nurses
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
