Question 6 (1 point) Complete this series - TRH - TSH - __ a) ADH b) cortisol c) insulin d) T_(3)-T_(4)

The correct answer is **d) **.TRH stands for Thyrotropin-Releasing Hormone. TSH stands for Thyroid-Stimulating Hormone. TRH stimulates the release of TSH, which in turn stimulates the thyroid gland to produce and release thyroid hormones, (triiodothyronine) and (thyroxine). Therefore, the series represents the cascade of hormone release in the thyroid pathway.
