2. A 4-month-old child has signs of rickets. Digestive disorders were not noted.The child has had adequate sun exposure, he has been receiving vitamin D, for2 months, but the manifestations of rickets did not diminish. Why did the doctorprescribe calcitriol to treat rickets in this child? For answer:a) draw a chart of hormone synthesis derived from vitamin D, and list thepossible causes of rickets in children;b) enumerate the target organs of the hormone and draw a chart of the hormonalsignal transduction;c) name the cause of rickets in this child and explain the doctor's prescription.fem

9. A child receiving adequate nutrition and vitamin D, shows signs of rickets. The blood calcium concentration is at the lower limit of normal. What are the possible causes of rickets in this child? For answer. a) describe the symptoms of rickets; b) name the hormones that regulate the calcium ions exchange in the body, and indicate their biological effects; c) provide a scheme for the hormone synthesis from vitamin D, and indicate the possible causes of rickets.
1. In thyrotoxicosis (Basedow’s diisease) excessive secretion of thyroid thyroxine hormone is observed and it is often accompanied by the increase in body tem- perature. Explain the reason for the increase in body temperature in this disease. For this purpose:a) draw the scheme of the process that maintains the temperature of the body;b) name the mechanism of the thyroxine effect on this process;c) show how the rate of О2 absorption by mitochon- dria of the cells will change in thyrotoxicosis.
3.On clinical examination of54-year-old woman the tumor of adrenal cortex was revealed. The glucoselevel in blood was increased. What is the main cause of hyperglycemia in this case? For answer:a)indicatethe hormone, which is elevated in the blood of patient;b)discuss this hormone synthesis and themechanism of signal transduction in target tissues; c)describe the metabolic pathways can be stimulated by this hormone in liver.

7. Name the hormone(s) produced in inadequate amounts that directly result in the following conditions. 1. diabetes insipidus 2. tetany 3. diabetes mellitus 4. abnormally small stature, normal proportions 5. myxedema (a lower-than-normal metabolic rate) 8. Name the hormone(s) produced in excessive amounts that directly result in the following conditions. 1. in the adult: large bones of the hands, feet, and face 2. nervousness, irregular pulse rate, sweating 3. demineralization of bones, spontaneous fractures
3. B. In the rare autoimmune Graves’ disease, antibodies are secreted which over-stimulate thyroid gland and cause hypersecretion (overproduction) of thyroid hormone. Predict how hyperactivity of thyroid glands would affect the plasma levels of active Thyroid hormone T3, Thyroid stimulating hormone (TSH), Thyrotropin releasing hormone (TRH), and explain why you would expect these changes in plasma T3, TSH and TRH in Graves’ disease with over-stimulation of thyroid glands?

JH, a 53 year-old female, had not been feeling well lately and suddenly started to feel acutely worse. Shestarted to have shortness of breath, and was experiencing an irregular heartbeat, chest pain, muscleweakness, and feelings of severe nausea. She called 911 and was taken to the hospital where bloodsamples were drawn. JH was diagnosed with hyperkalemia and ordered IV fluids. The IV fluids she was given contained calciumgluconate and insulin. Her potassium levels were monitored over a 24-hour period and were assummarized in Table 2 (attached) Using Table 2, which shows the patient’s plasma K+ concentrations over a 24-hour period, graph thechanges of K+ over time with computer software like Excel (not hand-drawn). Make sure to include an appropriate figure caption to explain what you haveobserved and follow scientific best practices for creating your graph. (You may consult graphs in publishedphysiology articles for inspiration!)
