Question

BlackTom AI · Accepted Answer

Question at position 24 asks which hormone is released from the thyroid gland in response to elevated blood calcium levels. 
Option 1: Aldosterone. This hormone is produced by the adrenal cortex and is primarily involved in regulating sodium and potassium balance and blood pressure, not calcium homeostasis, so it does not respond to high calcium.
Option 2: Parathyroid hormone (PTH). PTH is secreted by the parathyroid glands when calcium levels are low; it acts to raise calcium but it is not released by the thyroid, so this option is incorrect in the context of thyroid-derived calcium regulation.
Option 3: Insulin. Insulin is produced by the beta cells of the pancreas and governs glucose metabolism. It has no direct role in calcium regulation via the thyroid, making this choice incorrect.
Option 4: Thyroxine. Thyroxine (T4) is a thyroid hormone involved in metabolic rate and energy use, not in calcium sensing or release from calcium-regulating tissues, so this is not the hormone that responds to elevated calcium.
Option 5: Calcitonin. Calcitonin is produced by the parafollicular cells (C cells) of the thyroid gland and is released in response to high blood calcium levels; it helps to lower calcium by inhibiting osteoclast activity and reducing calcium reabsorption in the kidneys, aligning with calcium homeostasis.
In summary, understanding the roles: the thyroid gland houses C cells that secrete calcitonin in response to hypercalcemia, whereas the other hormones listed originate from different glands and have distinct primary functions unrelated to thyroid-mediated calcium sensing. The incorrect options either originate from other glands (adrenal, parathyroid, pancreas) or have metabolic roles unrelated to calcium regulation in the thyroid context, which explains why they do not fit the question’s premise.
