Adrenal Gland • Aldosterone • Na+ retention by kidney • Cortisol • Stress hormone • Adrenaline • Fight or flight response
Hypothalamus • GnRh/ Gonadotropin Releasing Hormone • Sex Drive
Ovaries • Estrogen • Stimulates the development of female secondary sex characteristics • Produces an environment suitable for fertilization, implantation, and growth of embryo
Pancreas • Insulin • Stimulates cells to take up glucose • Glucagon • Release glucose from glycogen • Maintain blood glucose levels
parathyroid • Parathyroid Hormone/ PTH • Regulates the level of blood calcium and phosphate ions
Pineal gland • Melatonin • Regulates circadian rhythms
pituitary • 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
Pituitary • 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
Testes • Testosterone • Stimulates the development of male secondary sex characteristics
thymus • Tyrosine • Produces T-Cells and lymphocytes
thyroid • Thyroxin • Stimulates the consumption of O2 and thus the metabolism • Calcitonin • Lowers blood calcium • Deposits to bone
I am Joe’s Pituitary Gland • 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.
