What levels of hormone production would you expect at each tier of the Hypothalamic-Pituitary-Thyroid (HPT) axis if a person has a functioning pituitary tumor?

A. low levels of thyroid stimulating hormone from the anterior pituitary, high levels of thyroid hormone from the thyroid, and low levels of thyrotropin-releasing hormone from the hypothalamus.

B. high levels of thyroid stimulating hormone from the anterior pituitary, high levels of thyroid hormone from the thyroid, and low levels of thyrotropin-releasing hormone from the hypothalamus.

C. low levels of thyroid stimulating hormone from the anterior pituitary, high levels of thyroid hormone from the thyroid, and high levels of thyrotropin-releasing hormone from the hypothalamus.

Answer #1

B. high levels of thyroid stimulating hormone from the anterior pituitary, high levels of thyroid hormone from the thyroid, and low levels of thyrotropin-releasing hormone from the hypothalamus.

The hypothalamus produce thyroid stimulating hormone releasing hormone which is responsible for the relase of TSH. But in this condition hypothalamus is unaffected and level is low. But with the functioning tumor on the pituitary the TSH production and release is higher. As a result the thyroid production is also higher

The hypothalamic-pituitary-adrenal axis includes corticotropin releasing hormone (CRH) from the hypothalamus, adrenocorticotropic hormone (ACTH) from the pituitary, and cortisol from the adrenal gland. In this system, CRH stimulates the release of ACTH, which stimulates the release of cortisol that exerts a negative feedback effect on both CRH and ACTH. Until only recently, there was no good tool to measure serum ACTH. Therefore, to evaluate whether pathologically high cortisol was related to ACTH, the “Dexamethasone suppression test” was invented. The elements...
