Question

11. Regarding the reflex pathway for parathyroid hormone (PTH) release, place the following statements in the proper sequence. a. calcium levels increase b. parathyroid hormone is sent to effector organs C. parathyroid cells detects deviation d. parathyroid cell initiates a response e. kidneys reabsorb calcium f. calcium levels decrease 12. List two reasons (besides strong bones) why Ca" is important to regulate 13. A decrease in plasma glucose is detected by the pancreas, the pancreas formulates a response, alpha cells of the pancreas release a hormone the increases plasma glucose levels. What hormone is this? 14. Decreased metabolic rate, decreased heat production, slowed pulse, depression, decreased protein production leading to brittle nails, thin hair, dry skin, myxedema, are all symptoms of thyroid disorder, called which means that too much/too little) thyroid hormones is being released. 15. List a few peptide hormones and steroid hormones. Which are lipophilic and which are lipophobic? Where are receptors for each type of hormone? What is the cellular mechanism of action for each type of hormone? 16. Estrogen, testosterone, cortisol are all hormones. 1. Insulin, glucagon, parathyroid hormone, oxytocin, vasopressin, growth hormone, adrenocorticotrophic hormone, luteinizing hormone are all hormones. 18. Thyroxine (T) and triiodothyronine (T3) are all hormones that mimic the hormone mechanism of action. 19. Epinephrine, norepinephrine, T. and T, are hormones. 20. All of the steroid hormones are derived from so they are similar in structure. 21. The pancreatic hormone that increases plasma glucose 22. The hormone that decreases plasma glucose 23. Hormone that controls water reabsorption by the kidneys 24. Hormone that controls plasma Ca concentration_ 25. Which of the following hormones are released by the anterior pituitary a. growth hormone b. follicle stimulating hormone C. thyroid stimulating hormone d. corticotropin releasing hormone e. estrogen f. oxytocin 8. vasopressin and these hormones 26. Epinephrine and norepinephrine are released by the activate the "fight or flight" response.

Answer 1

3) Calcium levels decrease iny) 2) Parathyroid cells intitiates a resbone 3) Parathyroid hormone is sent to on the effetor organs 4) Parathyroid detects deviation s) Kidney reabsorbs calcium 6) Calciom level increases. 100 db DX The parathyroid hormones are produce by the parathyroid gland This hormone increases the calium level as by causing calcium release that is stored in bones.
