Endocrine System Physiology Essay Sample

The undermentioned inquiries refer to Activity 1: Determining Baseline Metabolic Rates. 1. Which rat had the fastest baseline metabolic rate?
The normal rat had the fastest baseline metabolic rate.

2. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explicate your consequences.
The normal rat’s baseline metabolic rate was faster than that of the thyroidectomized rat’s baseline metabolic rate. 3. Compare the baseline metabolic rates for the hypophysectomised rat and the normal rat and explicate your consequences. The normal rat’s baseline metabolic rates were faster than that of the hypophysectomised rat’s baseline metabolic rate because it lacked thyroid-stimulating endocrines. The undermentioned inquiries refer to Activity 2: Determining the Effect of Thyroxine on Metabolic Rate. 4. What consequence did administrating tetraiodothyronine have on each of the rats?

It caused the metabolic rate to increase in all three rats.

5. Explain why tetraiodothyronine had these effects.
It is a thyroid-stimulating endocrine that causes more metamorphosis to happen.

The undermentioned inquiries refer to Activity 3: Determining the Effect of TSH on Metabolic Rate. 6. Was there a alteration in the metabolic rate of the thyroidectomized rat with the disposal of TSH? Explain your consequences. There was no alteration in the metabolic rate. It stayed the same as the baseline metabolic rate.

7. Make the consequences for the thyroidectomized rat indicate thyrotoxicosis or hypothyroidism? It indicated hypothyroidism since there is no longer any thyroid.

The undermentioned inquiries refer to Activity 4: Determining the Effect of Propylthiouracil on Metabolic Rate. 8. Describe the consequence of administrating propylthiouracil on each of the rats. and explicate why it had this consequence. It decreased the baseline metabolic rate in the normal and hypophysectomised rats. Propylthiouracil blocks the fond regard of I to tyrosine residues and interferes with the transition of tetraiodothyronine to triiodothyronine. hence. doing the baseline metabolic rate to diminish.

9. Make you believe the drug propylthiouracil is used to handle hypothyroidism or thyrotoxicosis? Explain your reply. It is used to handle thyrotoxicosis because propylthiauracil reduces or decreases the effects of tetraiodothyronine.

Hormone Replacement Therapy
The undermentioned inquiries refer to Activity 5: Hormone Replacement Therapy. 10. Explain why ovariectomized rats were used in this experiment and correlate this to their baseline T mark. Ovariectomized rats were used in this experiment because they have had their ovaries removed. hence. there is no estrogen being produced any longer. Their baseline T mark is -2. 6 because osteoporosis is evident.

11. Recapitulate your anticipations sing the effects of calcitonin and estrogen on bone denseness and explicate why you made those anticipations. I predicted that their bone denseness would better with the injections of calcitonin and estrogen because they are hormone replacing therapies. Calcitonin would assist with the production of osteoclasts and estrogen would assist increase the bone denseness.

12. Why was one of the ovariectomized rats injected with saline? One of the rats was injected with saline. which is merely H2O and salt. to be the controlled variable in the experiment. With saline. no affects would take topographic point.

13. What consequence did the disposal of estrogen injections have on the estrogen-treated rat? It increased bone denseness that resulted in osteopenia.
14. What consequence did the disposal of calcitonin injections have on the calcitonin-treated rat? It increased bone denseness that changed from osteoporosis to osteopenia. 15. How did your consequences compare to your anticipations?

My anticipations were accurate that the injections would assist increase bone denseness.

Insulin and Diabetes
The undermentioned inquiry refers to Activity 6: Obtaining a Glucose Standard Curve.

16. What is a glucose criterion curve. and how can you utilize this tool to find a concentration of glucose? The glucose criterion curve helps gives a mention for change overing optical denseness readings. You can utilize this to assist find how much glucose is present in someone’s blood sample.

The undermentioned inquiries refer to Activity 7: Measuring Fasting Plasma Glucose. 17. Which patient ( s ) had glucose reading ( s ) in the normal scope?
Patient # 1
18. Which patient ( s ) had glucose reading ( s ) in the diabetic scope?
Patients # 3 and # 5

19. Which patient ( s ) had glucose reading ( s ) in the impaired scope?
Patients # 2 and # 4
20. Describe the diagnosing for Patient 3.
The diagnosing for patient # 3 was Gestational Diabetes.
The undermentioned inquiries refer to Activity 8: Measurement Cortisol and Adrenocorticotropic Hormone. 21. Which patient would most probably be diagnosed with Cushing’s disease? Why?
Patient # 3 would most likely be diagnosed with Cushing’s disease because there were high degrees of hydrocortisone and ACTH in this patient.

22. Which two patients have hormone degrees characteristic of Cushing’s syndrome? Patients # 2 and # 5
