Question

What hormones need to be released in order to signal the thyroid gland to secrete thyroid hormone? Select all that apply.

a. TRH
b. TSH
c. ACTH
d. CRH

Answer 1

Thyroid Stimulating Hormone (TSH)

Step-by-step explanation:

TSH also called thyrotropin is released by the anterior pituitary gland and stimulates the thyroid glands to secrete the thyroid hormones throxine, triiodothyronine and tetraiodothyronine. Release of TSH is due to the stimulation of the anterior pituitary gland by the hypothalamus through the hormone Thyroid Releasing Hormone (TSH). Adrenocorticotropin hormone (ACTH) is released by the anterior pituitary gland due to hypothalamic stimulation through the hormone Corticotropin Hormone (CRH) that helps in synthesis and release of ACTH.
