Chapter 15, Problem 1CT
Addison’s disease develops when the adrenal cortex does not secrete enough mineralocorticoids and glucocorticoids. President John F. Kennedy was diagnosed with the disease when he was a young man. Before he started treatment with hormone replacement therapy, he was hypoglycemic and lost weight. Which missing hormone was responsible for his weight loss? How might Addison’s disease have affected his blood pressure?

Addison’s disease develops when the adrenal cortex does not secrete enough mineralocorticoids and glucocorticoids. President John F. Kennedy was diagnosed with the disease when he was a young man. Before he started treatment with hormone replacement therapy, he was hypoglycemic and lost weight. Which missing hormone was responsible for his weight loss? How might Addison’s disease have affected his blood pressure?
In Graves' disease, the body attacks the thyroid gland tissue and causes it to overproduce thyroid hormones, resulting in elevated blood levels of T3 and T4.
Which of the following statements would be TRUE?
Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TRH and the Anterior Pituitary Gland would release more TSH.
Since blood levels of thyroid hormones are elevated, the hypothalamus would release more TRH and the Anterior Pituitary Gland would then stop releasing TSH.
Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TRH and the Anterior Pituitary Gland would not release TSH.
Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TSH and the Anterior Pituitary Gland would not release TRH.
Which one of the following statements about T3 is FALSE?
1) It is thought to be the most active thyroid hormone.
2) It may be elevated to a greater extent than T4 in hyperthyroidism.
3) It is not bound to serum proteins.
4) It is commonly decreased in patients with nonthyroidal illness.

- A physician sees a patient whose symptoms include sluggishness, depression, and intolerance to cold. After eliminating other possible causes, the doctor diagnoses a hormone problem. What disorder fits the symptoms? Why does the doctor suspect that the underlying cause is a malfunction of the anterior pituitary gland?arrow_forward(human physiology) 1) Match the insulin types (1-3) with the plots (A-C)? Explain? 2) Oral administration (e.g. in the form of pills) of insulin and subcutaneous administration, which is more effective? Why? 3) Why are elderly, sedentary, obese and regular smokers at high risk of diabetes?arrow_forwardFor our patient John with diabetes type II, he can make insulin but his body cells can be resistant to this insulin. Note: activated insulin receptors will activate glucose receptors. How is John’s diabetes related to the endocrine system?arrow_forward
- 1) Hormone pathologies often manifest with elevated or lower hormones. The underlying cause may differ. What symptoms would be associated with hyperthyroidism? 2) Autoimmune disease in which auto-antibodies stimulate the TSH receptor (TSHR) on the thyroid gland. How would this affect levels of TRH, TSH, and TH? Draw out the H-P-T axis to illustrate changes in each hormone. 3) What symptoms would be associated with hypothyroidism? 4) How could this disease be treated? When the thyroid cells are destroyed, they cannot make hormones anymore and TH replacement needs to be given.arrow_forwardTake thyroid hormones as an example of hormones and their properties. Thyroid hormone is highly bound to proteins in the blood. What is the benefit of such protein binding? What effect does protein binding have on the activity of the hormone? Name a gland other than the thyroid gland that is involved in regulating thyroid hormone production?arrow_forwardInsulin is a peptide hormone that is lacking from the body in some forms of diabetes mellitus. Why do people with this type of diabetes inject insulin rather than consuming an insulin pill?arrow_forward
- A woman affected by type 1 (insulin-dependent) diabetes miscalculates and injects herself with too much insulin. She soon begins to feel confused and sluggish. She calls for medical assistance and injects herself with the glucagon her doctor prescribed for such an emergency. When an ambulance arrives, she is given dextrose (a sugar) intravenously. How did the excess insulin cause her symptoms? How did the glucagon injection and the intravenous sugar help reverse them?arrow_forwardThyroid hormones are important in regulating the body’s basal metabolic rate. Thyroid hormones are lipid-soluble and have a long half-life.What are the advantages and disadvantages of a long half-life for thyroidhormones, compared with a short half-life?arrow_forwardState what the different parts of the pituitary gland are called and how they differ. b) Explain the physiological significance of the portal system of the hypothalamus and pituitary gland c) What hormones are produced by different parts of the pituitary gland? Enter in the image below. What effects do these hormones have on the body? Give at least one example of a function for each hormone.arrow_forward
- A person develops a rare autoimmune condition during early adulthood which targets only the cells in the thyroid responsible for the release of calcitonin. Which of the following is most likely to describe the patient's blood Ca2+ concentration? This person is asymptomatic and has normal blood Ca" levels. This person has hypocalcemia (low blood Ca) because osteoclasts are not resorbing bone. This person has hypocalcemia (low blood Ca) because of reduced Ca absorption in the gastrointestinal tract This person has hypercalcemia (high blood Ca) because osteoblasts are not depositing bone.arrow_forwardDescribe the functions of the following hormones: TSH, thyroxine, calcitonin, PTH, ACTH, cortisol, insulin, glucagon, hGH, ADH, epinephrine, and aldosterone.arrow_forward2. State which hormone is probably responsible for each physiological phenomenon described below and explain why. a) Blood glucose levels remained constant even though someone went 20 hours without eating or drinking. b) Heart rate and breathing rate increase when someone is awoken by a loud noise in the middle of the night. c) A grown man's jaw and forehead become thick and deformed.arrow_forward
