UTA 5315 Exam 4 1. Thyroid Hor- mones T3, T4, calcitonin 2. Iodine Takes 1 mg of per week to form thyroxine 3. 2-3 months How long does thyroid failure take to develop symptoms due to reserves of thyroglobulin? 4. Antagonize T3 and T4 insulin 5. Stimulates T3 cardiac contractile proteins and the Na/K pump and Ca pump 6. Calcitonin Lowers blood calcium levels by preventing bone resorp - tion effects of PTH 7. TSH Controls uptake of iodine 8. adrenal cortex aldosterone, cortisol, androgens are produced by the 9. Inhibit Glucocorticoids ADH, cellular uptake of glu- cose, and protein synthesis 10. Aldosterone "salt-retaining hormone" which promotes the retention of Na+ by the kidneys. na+ retention promotes water retention, which promotes a higher blood volume and pressure 11. Angiotensin II increases blood pressure by stimulating kidneys to reab- sorb more water and by releasing aldosterone 12. Adrenal Medulla secretes epinephrine and norepinephrine and dopamine 13. Epinephrine Which is more potent: epinephrine or norepinephrine? 14. Catecholamines All increase BP, HR, RR, glucose, cellu- lar metabolism, and cause vasoconstriction 15. insulin, glucagon, somatostatin, gastrin Pancreas hor- mones 16. Somatostatin Regulates the alpha and beta cells by inhibiting insulin and glucagon 17. Amylin regulates glucose by delaying gastric emptying and sup- pressing glucagon secretion; promotes satiety (feeling full) 18. Visceral WAT Causes dysfunction in regulation and leads to the obesity related complications 19. Hypothalamus regulates body temperature, hunger, thirst, and sexual behavior 20. Leptin A hormone produced by adipose (fat) cells that acts as a satiety factor in regulating appetite. 21. leptin resistance a condition in which higher -than-normal blood levels of the hormone leptin do not produce the expected physio - logical response 22. Adiponectin enhances sensitivity to insulin, decreased in obesity con- tributing to insulin resistance and DM 2. 23. Ghrelin Decreased in obesity causing a blunted response to eating (does not feel full) 24. Grave's Disease an autoimmune disorder that is caused by hyperthy - roidism and is characterized by goiter and/or exophthal - mos 25. Grave's Disease Antibodies produced by host bind to host's own thyroid gland cells. Antibody binding over -stimulates the thyroid gland. 26. nodular thyroid disease Nodules secrete extra hormones, insidious, do not expe - rience exophthalmos or pretibial myxedema
