    Q: the addition of potassium iodide as a nutritional supplement to common table salt would most directly affect the function of which of these glands?

    A: thyroid

    I know the thyroid gland produces thyroid hormones (i.e throxin) which is necessary for growth and neurological development in children. It also produces calcitonin to inhibit the release of Ca2+ from the bone. But, how does it actually involve with potassium iodide?

    I first picked the choice answer "aldosterone" which stimulates the secretion of K+ since I though high K+ concentration would cause adrenal cortex to make more aldosterone.

    Potassium is really everywhere in the body and wouldn't be very specific to the Kidneys for this question. Whenever you hear Iodide though, think thyroid gland. FYI, calcitonin is produced in the parathyroid gland, not the thyroid. (Just in case that every comes up) GL! :thumbup:

    Iodine is needed for the synthesis of T3 (triiodothyronine) and T4 (tetraiodothyronine).

    thanks guys, now i got it

    What's the function of thyroxin from thyroid gland ? Is thyorxin a type of T4?

    btw, I am 100% sure Calcitonine is secreted by thyroid gland as I am looking at my kaplan book right now :D unless kaplan is wrong?

    thyroxine is the major form of t4 in the blood. calcitonin=thyroid.
