Adrenal Cortex Hormone Production Stimulated by ACTH
The question asks to identify the hormone secreted by the anterior pituitary gland that stimulates the adrenal cortex to produce glucocorticoids and androgens.
The anterior pituitary gland releases several tropic hormones that act on other endocrine glands. The specific hormone that targets the adrenal cortex is Adrenocorticotropic hormone (ACTH).
- ACTH (Adrenocorticotropic hormone) is produced and secreted by the anterior pituitary gland.
- ACTH travels through the bloodstream to the adrenal cortex (the outer layer of the adrenal gland).
- In the adrenal cortex, ACTH stimulates the synthesis and secretion of key steroid hormones, primarily:
- Glucocorticoids (e.g., cortisol)
- Androgens (e.g., DHEA)
Therefore, ACTH is the hormone responsible for stimulating the production of glucocorticoids and androgens by the adrenal cortex.
Comparing this with the options provided:
- GH (Growth Hormone) primarily affects growth and metabolism.
- FSH (Follicle-Stimulating Hormone) acts on the gonads.
- TSH (Thyroid-Stimulating Hormone) acts on the thyroid gland.
- ACTH (Adrenocorticotropic hormone) acts on the adrenal cortex.
The correct option is ACTH.
