4. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.

6.  Aldosterone  Na+ retention by kidney  Cortisol  Stress hormone  Adrenaline  Fight or flight response

7.  GnRh / Gonadotropin Releasing Hormone  Sex Drive

8.  Estrogen  Stimulates the development of female secondary sex characteristics  Produces an environment suitable for fertilization, implantation, and growth of embryo

9.  Insulin  Stimulates cells to take up glucose  Glucagon  Release glucose from glycogen  Maintain blood glucose levels

10.  Parathyroid Hormone/ PTH  Regulates the level of blood calcium and phosphate ions

11.  Melatonin  Regulates circadian rhythms

12.  Oxytocin  Uterine contraction/milk production  Vasopressin/ADH: Antidiuretic hormone  Causes kidneys to reduce water excretion  Growth Hormone/ Gonadotropin/ GH  Stimulates increase in size and mitotic rate of body cells, increases fat utilization  Promotes long bone growth

13.  Follicle Stimulating Hormone/ FSH  Development of ovarian follicles, stimulates follicular cells to secrete estrogen  In men, stimulation of sperm production  Luteinizing Hormone/ LH  Promotes secretion of sex hormones  In women, promotes egg release  Prolactin/PRL  Sustains milk production after birth

14.  Testosterone  Stimulates the development of male secondary sex characteristics

15.  Tyrosine  Produces T-Cells and lymphocytes

16.  Thyroxin  Stimulates the consumption of O2 and thus the metabolism  Calcitonin  Lowers blood calcium  Deposits to bone

17. 1. Describe the pituitary gland. 2. Explain the pituitary gland’s role in the endocrine system. 3. List at least three hormones secreted by the pituitary gland. 4. What did doctors originally identify as the function of the pituitary gland and why? 5. Why is it believed that the pituitary gland is the answer to the cancer riddle? 6. Discuss one possible side affect of an injury to the pituitary gland.
