Activity 11: Homeostatic Imbalances of Thyroid Function
Name:
Instructor:
Date:
PREDICTIONS
1. TSH levels in patients with primary hypothyroidism are:
2. Thyroxine (T4) levels in patients with primary hypothyroidism are:
3. TSH levels in patients with secondary hypothyroidism are:
4. Thyroxine (T4) levels in patients with secondary hypothyroidism are:
5. TSH levels in patients with hyperthyroidism are:
6. Thyroxine (T4) levels in patients with hyperthyroidism are:
MATERIALS AND METHODS
1. Dependent Variable
2. Independent variable
3. Controlled variable
4. Why was RIA used to measure T4 while IRMA was used to measure TSH?
5. How was it used to observe relative amount of iodine accumulated by thyroid gland?
RESULTS
See Table 2: Concentration of Thyroxine and Thyroid Stimulating Hormone (TSH) in the blood serum.
1. The normal range for total amount of T4 in serum is 0.05 ÷0.14 mg/L. For each patient, type in their serum T4 concentration and indicate if it is lower, within, or higher than the normal range.
a. Patient with primary hypothyroidism b. Patient with secondary hypothyroidism c. Patient with hyperthyroidism
2. The normal range for serum TSH is 0.35 ÷ 4.5 mIU/L . For each patient, type in her serum TSH concentration and indicate if it is lower, within, or higher than the normal range.
a. Patient with primary hypothyroidism b. Patient with secondary hypothyroidism c. Patient with hyperthyroidism
3. For each patient, state whether her thyroid image indicates whether their iodine uptake is low, normal, or high.
a. Patient with primary hypothyroidism b. Patient with secondary hypothyroidism c. Patient with hyperthyroidism
DISCUSSION
1. For each subject, indicate whether her TRH levels would be low, normal, or high. Please explain your decision. Discuss negative feedback control in your answer.
a. Subject with primary hypothyroidism b. Subject with secondary hypothyroidism c.
