Hormones and Organs that secrete Th: Feb 27, 2014 LT: I can identify and describe the role of hormones of the Endocrine system. 1. 2. 4. 3. 14. 5. 13. 6. 12. 11. 8. 10. 9. 7. Aldosterone Na+ retention by kidney Cortisol Stress hormone Adrenaline Fight or flight response GnRh/ Gonadotropin Releasing Hormone Sex Drive Estrogen Stimulates the development of female secondary sex characteristics Produces an environment suitable for fertilization, implantation, and growth of embryo Insulin Stimulates cells to take up glucose Glucagon Release glucose from glycogen Maintain blood glucose levels Parathyroid Hormone/ PTH Regulates the level of blood calcium and phosphate ions Melatonin Regulates circadian rhythms Growth Oxytocin Uterine contraction/milk production Vasopressin/ADH: Antidiuretic hormone Causes kidneys to reduce water excretion Hormone/ Gonadotropin/ GH Stimulates increase in size and mitotic rate of body cells, increases fat utilization Promotes long bone growth 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 Testosterone Stimulates the development of male secondary sex characteristics Tyrosine Produces T-Cells and lymphocytes Thyroxin Stimulates the consumption of O2 and thus the metabolism Calcitonin Lowers blood calcium Deposits to bone 1. 2. 3. 4. 5. 6. Describe the pituitary gland. Explain the pituitary gland’s role in the endocrine system. List at least three hormones secreted by the pituitary gland. What did doctors originally identify as the function of the pituitary gland and why? Why is it believed that the pituitary gland is the answer to the cancer riddle? Discuss one possible side affect of an injury to the pituitary gland.
