Question 3

The third image shows a person with an enlarged thyroid gland (goiter). Which of the following best explains why a goiter can result from inadequate dietary iodine?

Accepted Answer

Low iodine prevents the synthesis of thyroid hormone, leading to increased TSH stimulation and thyroid gland growth

Question 4

Which hormone is represented by label 'B' in the second image, and what is its effect?

Accepted Answer

Thyroid-stimulating hormone (TSH); stimulates the thyroid gland to release thyroid hormones

Question 5

Which hormone is represented by label 'C' in the second image, and what is its primary effect on target cells?

Accepted Answer

Thyroid hormone (TH); increases the rate of cellular metabolism

Question 6

Which gland is labeled 'D' in the first image, and what hormone does it primarily produce?

Accepted Answer

Thyroid gland; produces thyroid hormone (TH)

Question 7

Which of the following best describes the feedback mechanism illustrated in the second image?

Accepted Answer

Negative feedback; thyroid hormone inhibits both the hypothalamus and anterior pituitary

Question 8

If the gland labeled 'H' in the first image is damaged, which hormone's secretion would be most directly affected?

Accepted Answer

Insulin

Question 9

A patient presents with symptoms of hypothyroidism and an enlarged thyroid gland as seen in the third image. Which dietary intervention would most likely resolve the underlying cause?

Accepted Answer

Increasing dietary iodine intake

Question 10

Which gland is labeled 'A' in the first image, and what hormone does it secrete that regulates circadian rhythms?

Accepted Answer

Question 11

Which gland is labeled 'I' in the first image, and what is its primary endocrine function?
