Which statement about the thyroid gland is true?

Question

Quizplus · Accepted Answer

In hyperthyroidism, an antibody can bind to the receptors for thyroid-stimulating hormone (TSH), causing uncontrolled release of thyroxine. This results in an overactive thyroid gland and can lead to a goiter. A goiter can also occur in hypothyroidism due to the lack of iodine, which is necessary for proper thyroid function. A low metabolic rate is a symptom of hypothyroidism, not hyperthyroidism. In hyperthyroidism, blood levels of triiodothyronine (T3) are typically high, not low.
