Study Notes

Hypothalamic Regulation of Anterior Pituitary

Hypothalamic release hormones (GHRH, CRH, TRH, GnRH) stimulate the anterior pituitary gland to secrete trophic hormones.
Hypothalamic inhibitory hormones (GHIH, PIH) inhibit the secretion of trophic hormones from the anterior pituitary gland.

Anterior Pituitary Function

The anterior pituitary gland secretes trophic hormones, which act on other endocrine glands to stimulate hormone production.
Trophic hormones secreted by the anterior pituitary gland include:
- ACTH (stimulates adrenal cortex)
- TSH (stimulates thyroid gland)
- FSH and LH (stimulate ovaries and testes)

Studying That Suits You

Description

Test your knowledge of the hypothalamic-pituitary axis and how it regulates hormone secretion in the body. Learn about the role of releasing and inhibiting hormones, and how they affect the anterior pituitary gland's secretion of trophic hormones.
