Which hormone is released by the anterior pituitary in response to corticotropin-releasing hormone (CRH) from the hypothalamus?

A.

Thyroid-stimulating hormone (TSH)

B.

Prolactin

C.

Growth hormone (GH)

D.

Adrenocorticotropic hormone (ACTH)

Answer and Explanation

The Correct Answer is D

A. Thyroid-stimulating hormone (TSH): TSH is released by the anterior pituitary in response to thyrotropin-releasing hormone (TRH) from the hypothalamus, not CRH.
B. Prolactin: Prolactin release is primarily inhibited by dopamine and can be stimulated by TRH and other factors, but it is not the principal anterior pituitary response to CRH.
C. Growth hormone (GH): GH secretion is regulated mainly by growth hormone–releasing hormone (GHRH) and somatostatin from the hypothalamus, not by CRH.
D. Adrenocorticotropic hormone (ACTH): ACTH is secreted by the anterior pituitary in response to corticotropin-releasing hormone (CRH) from the hypothalamus and stimulates the adrenal cortex to produce cortisol.

Correct Answer is C

Explanation

A. Aldosterone:Aldosterone primarily regulates sodium and potassium balance and blood pressure, not the classic metabolic stress response.
B. Insulin:Insulin regulates blood glucose uptake and metabolism; it is not the primary hormone mediating the stress response.
C. Cortisol:Cortisol, produced via the HPA axis, mobilizes energy, modulates immune responses, and is the principal glucocorticoid involved in the stress response.
D. Thyroxine:Thyroxine (T4) controls basal metabolic rate and growth but is not the primary hormone of the acute stress response.

Correct Answer is A

Explanation

A. Parathyroid gland:The parathyroid glands secrete parathyroid hormone (PTH), the principal hormone that raises blood calcium by increasing bone resorption, renal calcium reabsorption, and activation of vitamin D.
B. Thyroid gland:The thyroid gland primarily regulates metabolism (thyroid hormones) and secretes calcitonin, which lowers blood calcium but plays a lesser role than PTH in everyday calcium regulation.
C. Pituitary gland:The pituitary regulates many endocrine glands via trophic hormones but does not directly control minute-to-minute calcium regulation.
D. Adrenal gland:The adrenal glands regulate stress responses, salt balance (aldosterone), and metabolism (cortisol), but not primary calcium homeostasis.
