Multiple Choice
Which of the following is the first step in the formation of thyroid hormones?
Uptake of iodine by follicular cells
2
Multiple Choice
What is the role of thyroglobulin (TGB) in thyroid hormone formation?
It transports thyroid hormones in the blood
It is synthesized and released into the colloid where it gets iodinated
It converts T4 to T3
It increases the release of TSH
3
Multiple Choice
Where does the oxidation of iodide occur in the formation of thyroid hormones?
in the blood
Inside the thyroid follicular cells
In the colloid of the thyroid follicles
In the liver
4
Multiple Choice
What happens after thyroglobulin (TGB) is iodinated in the colloid?
it is converted into T3 and T4 by combining T1 and T2
It is secreted directly into the bloodstream
It undergoes transformation into calcitonin
It is converted iodine
5
Multiple Choice
What is the final step in the thyroid hormone formation process?
Secretion of T3 and T4 into the blood
Iodine trapping by follicular cells
Iodination of TGB tyrosines

Multiple Choice
What is the primary role of thyroid hormones in growth and development?
They inhibit growth in children
They stimulate growth in conjunction with human growth hormone (hGH) and insulin
