question 17
excessive thyroid hormones increase the bodys sensitivity to which of the following?
calcitonin
estrogens
gonadotropins
catecholamines

Explanation:

Excessive thyroid hormones enhance the body's sensitivity to catecholamines (such as epinephrine and norepinephrine). This is because thyroid hormones up - regulate beta - adrenergic receptors. Calcitonin is involved in calcium regulation, estrogens in the female reproductive system and secondary sexual characteristics, and gonadotropins (like FSH and LH) in the reproductive system. None of these have the receptor - upregulating interaction with thyroid hormones like catecholamines do.

Answer:

Catecholamines
