Question 3

Which type of goiter (enlarged thyroid) can be reduced by the addition of iodine to the diet?

Accepted Answer

Hypothyroid goiter occurs due to low levels of functional thyroxine and high levels of thyrotropin. The addition of iodine to the diet can help reduce this type of goiter as iodine is required for the production of thyroxine. When the thyroid gland does not have sufficient iodine, it cannot produce enough thyroxine, resulting in goiter. However, iodine will not be helpful in reducing goiter caused by hyperthyroidism (either due to high levels of thyroxine or failure of thyroxine to turn off pituitary secretion of TSH), as the underlying cause is not a lack of iodine but rather an overproduction of thyroid hormone.

Question 4

Which of the following hormones elevates blood calcium?

Accepted Answer

Parathyroid hormone elevates blood calcium by promoting the release of calcium from bones, enhancing absorption of calcium from the small intestine, and reducing excretion of calcium in urine. Thyroxine, calcitonin, oxytocin, and vasopressin do not have direct effects on blood calcium levels.

Question 10

The parathyroid glands are involved in regulation of blood levels of

Accepted Answer

The parathyroid glands secrete parathyroid hormone (PTH), which plays a key role in regulating blood levels of calcium. PTH increases calcium levels by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and decreasing calcium excretion in the kidneys.

Question 16

The hormone responsible for releasing calcium from bone into the bloodstream is

Accepted Answer

Parathyroid hormone (PTH) is the hormone responsible for releasing calcium from bone into the bloodstream. PTH is released by the parathyroid gland when blood calcium levels are low, and acts on bone to stimulate the activity of bone-resorbing cells called osteoclasts, which break down bone and release calcium into the bloodstream.
