Effect of thyroxine on the thyroidectomized rats metabolic rate
Effect of thyroxine on the thyroidectomized rats

1. Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? 2. Why did the metabolic rates differ? Check all that apply: 3.Back 9 THE EFFECT OF PROPYLTHIOURACIL ON THE RATS MADE THE METABOLIC RATES REMAIN LOW. THIS IS BECAUSE PROPYLTHIOURACIL INHIBITS THYROXINE. SO THYROXINE IS NOT STIMULATED IN ANY RAT AND THE RATS THEREFORE CAN NOT MAINTAIN METABOLISM AND BODY HEAT MAKING NO CHANGE IN THE RATES.

Front 14 ACTIVITY 5: WHAT EFFECT DID THE ADMINISTRATION OF ESTROGEN INJECTIONS HAVE ON THE ESTROGEN -TREATED RAT? back 14 IT IMPROVED BONE DENSITY FROM -2.6 OSTEOPOROSIS TO -1.9 OSTEOPENIA. front 15 ACTIVITY 5: WHAT EFFECT DID THE ADMINISTRATION OF CALCITONIN INJECTIONS HAVE ON THE CALCITONIN -TREATED RATS?THIS SI BECAUSE THE PITUITARY GLAND HAS BEEN REMOVED. PITUITARY GLAND SECRETES TSH THAT CONTROLS PRODUCTION AND RELEASE OF THYROXINE, WITHOUT IT THE METABOLIC RATE IS EFFECTED AND IS SLOWER. front 4 ACTIVITY 2: WHAT EFFECT DID ADMINISTERING THYROXINE HAVE ON EACH OF THE RATS?

Back 12 I PREDICTED THAT THEY WOULD BOTH IMPROVE THE BONE DENSITY. BECAUSE ADMINISTRATING ESTROGEN OR CALCITONIN ARE FORMS OF HORMONE REPLACEMENT THERAPY. ESTROGEN WILL INCREASE BONE DENSITY AND CALCITONIN WILL INHIBIT OSTEOCLAST ACTIVITY AND STIMULATE CALCIUM UPTAKE FOR DEPOSIT IN BONE.Front 11 ACTIVITY 5: EXPLAIN WHY OVARIECTOMIZED RATS WERE USED IN THIS EXPERIMENT AND CORRELATE THIS TO THEIR BASELINCORE. back 11 THREE OVARIECTOMIZED RATS WERE USED BECASUE THEY ARE NO LONGER PRODUCING ESTROGEN DUE TO THE REMOVAL OF THEIR OVARIES.

Front 23 ACTIVITY 8: WHICH TWO PATIENT 'S HAVE HORMONE LEVELS CHARACTERISTIC OF CUSHING 'S SYNDROME? back 23 PATIENT 2 AND 5 HAVE HORMONE LEVELS THAT ARE SIMILAR TO THOSE OF CUSHING 'S SYNDROME.19. What was the effect of administering insulin to the experimental animal? 20. Insulin is secreted from which cells in the pancreas? Some questions in this exercise may have more than one correct answer.

WHY? back 25 PATIENT 4 WOULD MOST LIKELY BE DIAGNOSED WITH ADDISON 'S DISEASE. THE PATIENT HAS LOW CORTISOL BUT ACTH LEVELS WERE HIGH. IN THIS DISEASE THE LOW CORTISOL IS DIRECTLY DUE TO GRADUAL DESTRUCTION OF THE ADRENAL CORTEX, AND ACTH LEVELS ARE TYPICALLY ELEVATED AOMPENSATORY EFFECT.9. Refer to Activity 4: Determining the Effect of Propylthiouracil on Metabolic Rate. What effect did an injection of propylthiouracil have on the metabolic rate of the normal rat? 10. What was the effect of the propylthiouracil on the thyroidectomized rat?

17. What is the condition that the injection of alloxan caused in the experimental rat? 18. What is the effect of administering insulin to the control animal? Check all that apply.What was the effect of thyroxine injections on the thyroidectomized rat s BMR? How does the BMR in this case compare with the normal rat s BMR? Was the.

How did the thyroxine affect the normal rat s metabolic rate? It caused. What was the effect of thyroxine on the thyroidectomized rat s metabolic rate? Thyroxine.Front 3 ACTIVITY 1: COMPARE THE BASELINE METABOLIC RATES FOR THE HYPOPHYSECTOMIZED RAT AND THE NORMAL RATAND EXPLAIN YOUR RESULTS. back 3 THE HYPOPHYSECTOMIZED RATS BMR WAS SLOWER THEN THE NORMAL RAT.

L thyroxine / euthyrox ®

Back 18 PATIENT 1 (TUBE 1) HAEADING OF 101MG/DL, WAY BELOW 110 MG/DL SO IT FALLS IN THE NORMAL RANGE. front 19 ACTIVITY 7: WHICH PATIENT (S) HAD GLUCOSE READING (S) IN THE DIABETIC RANGE?Back 4. THE THYROXINE MADE THE RATS METABOLIC RATES VERY CLOSELY SIMILIAR. THE EFFECTS OF THE THYROXINE INCREASED THE METABOLIC RATES OF EACH RAT COMPARED TO ACTIVITY 1. front 5 Ok, so youre using my notecards which is great.

METABOLIC EFFECTS OF THYROXINE INJECTED INTO NORMAL, THIOURACIL -TREATED AND THYROIDECTOMIZED RATS. S. B. BARKER, C. E. KIELY.7. How did the metabolic rate of the thyroidectomized rat injected with TSH compare to its baseline metabolic rate? 8. What was the oxygen consumption per hour for the hypophysectomized rat injected with TSH?

Front 8 ACTIVITY 3: DID THE RESULTS OR THE THYROIDECTOMIZED RAT INDICATE HYPERTHYROIDISM OR HYPOTHYROIDISM? back 8. IT INDICATED HYPOTHYROIDISM front 9 ACTIVITY 4: DESCRIBE THE EFFECT OF ADMINISTERING PROPYLTHIOURACIL ON EACH OF THE RATS, AND EXPLAIN WHY IT HAD THIS EFFECT.Front 7 ACTIVITY 3: WAS THERHANGE IN THE METABOLIC RATE OF THE THYROIDECTOMIZED RAT WITH THE ADMINISTRATION OF TSH? EXPLAIN YOUR RESULTS. back 7 IT INCREASED BUT HARDLY AT ALL. IF THE RAT HAS NO THYROID THE TSH IS NOT GOING TO STIMULATE ANYTHING, SO THYROXINE WONT BE RELEASED AND THERE WAS HARDLY NO CHANGE.

11. Refer to Activity 5: Hormone Replacement Therapy. How does the uterus weight of the rat that received estrogen differ from the uterus weight of the rat that received saline? 12.Loading.

Refer to Activity 2: Determining the Effect of Thyroxine on Metabolic Rate. How did the thyroxine affect the normal rat's metabolic rate? 4. What was the effect of thyroxine on the thyroidectomized rat's metabolic rate?How did the thyroxine affect the normal rat s metabolic rate?. 4. What was the effect of thyroxine on the thyroidectomized rat s metabolic rate?

Front 13 ACTIVITY 5: WHY WAS ONE OF THE OVERIECTOMIZED RATS INJECTED WITH SALINE? back 13 THIS IS THE CONTROLLED PORTION OF THE EXPERIMENT SINCE SALINE IS JUST SALT AND WATER IT WOULDN 'T CASE ANY AFFECT ON THE RAT.Front 10 ACTIVITY 4: DO YOU THINK THE DRUG PROPYLTHIOURACIL IS USED TO TREAT HYPOTHYROIDISM OR HYPERTHYROIDISM? EXPLAIN YOUR ANSWER. back 10. IT IS USED TO TREAT HYPERTHYROIDISM. SINCE IT INHIBITS THYROXINE IT CAN BE USED TO CONTROL THYROID PRODUCTION OF THYROXINE, AND FURTHER CONTROL HYPERTHYROIDISM.

It can be for any subject or class. Thanks and dont forget to rate my helpfulness! front 6 ACTIVITY 2: EXPLAIN WHY THYROXINE HAD THESE EFFECTS. back 6. THYROXINE IS THE MOST IMPORTANT HORMONE IN MAINTAINING METABOLISM AND BODY HEAT.Front 21 ACTIVITY 7: DESCRIBE THE DIAGNOSIS FOR PATIENT 3. back 21 TYPE 2 DIABETES MELLITUS - GLUCOSE REMAINS IN BLOODSTREAM UNABLE TO BE TAKEN UP BY THE BODY 'S CELLS TO SERVE AS THE PRIMARY FUEL FOR METABOLISM.

5. What was the effect of thyroxine on the hypophysectomized rat? 6. Refer to Activity 3: Determining the Effect of TSH on Metabolic Rate. What is the effect of TSH on the normal rat's metabolic rate?THE THYROIDECTOMIZED RATS BMR WAS SLOWER THEN THE. THE. EFFECTS OF THE THYROXINE INCREASED THE METABOLIC RATES OF. EACH.
