Question at position 2 Elevated levels of calcium ion in the blood would stimulate:growth hormonetestosteronecalcitoninthyroid hormone

BlackTom AI · Accepted Answer

Consider the physiology question: Elevated levels of calcium ion in the blood would stimulate which hormone?
Option 1: growth hormone. While GH has metabolic effects, it is not primarily a direct regulator of calcium homeostasis in response to hypercalcemia. Its secretion is more closely tied to growth, metabolism, and sleep, not calcium sensing.
Option 2: testosterone. Testosterone is a sex hormone; its release is controlled by the hypothalamic-pituitary-gonadal axis and is not a primary responder to high calcium levels in the blood.
Option 3: calcitonin. Calcitonin is produced by the thyroid's parafollicular C cells and is specifically released in response to elevated blood calcium to help lower calcium levels by inhibiting osteoclast activity and promoting calcium deposition in bone. This makes calcitonin the direct calcium-homeostasis regulator among the options.
Option 4: thyroid hormone. Thyroid hormone regulates metabolic rate and has broad effects, but it is not acutely stimulated by high calcium levels to control calcium homeostasis. Its secretion is tied to thyroid-stimulating hormone signaling rather than hypercalcemia per se.
Thus, each option is evaluated against the direct role of maintaining calcium balance. The most accurate choice reflecting a calcium-responsive hormone that lowers blood calcium is calcitonin, whereas the other hormones do not respond specifically to elevated calcium in this immediate sense.
