If the thyroid gland is unable to produce iodinated thyroglobulin, what is the effect on hormone production?

Triiodothyronine (T3) and thyroxine (T4) production continues uninterrupted.

Excess triiodothyronine (T3) and thyroxine (T4) hormones are produced.

Less triiodothyronine (T3) and thyroxine (T4) hormones are produced.

Less thyroid-stimulating hormone (TSH) is released.

Answer and Explanation

The Correct Answer is C

a) Triiodothyronine (T3) and thyroxine (T4) production continues uninterrupted.
Iodinated thyroglobulin is essential for producing T3 and T4.

b) Excess triiodothyronine (T3) and thyroxine (T4) hormones are produced.
A lack of iodinated thyroglobulin leads to decreased production.

c) Less triiodothyronine (T3) and thyroxine (T4) hormones are produced.
Without iodinated thyroglobulin, the thyroid cannot synthesize sufficient T3 and T4, leading to hypothyroidism.

d) Less thyroid-stimulating hormone (TSH) is released.
TSH levels would actually increase due to lack of negative feedback from low T3 and T4 levels.

Correct Answer is C,B,A

No explanation

A. hypercalcemia B. cold temperatures C. hypocalcemia D. low basal metabolic rate

Correct Answer is C

Explanation

a) Hypercalcemia: High calcium levels inhibit PTH secretion via negative feedback.

b) Cold temperatures: PTH release is not influenced by ambient temperature.

c) Hypocalcemia: Low calcium levels stimulate the parathyroid glands to release PTH to increase calcium concentration.

d) Low basal metabolic rate: This relates more to thyroid hormone activity than to calcium regulation.
