Best answer: How do the releasing hormones get to the anterior pituitary gland?

These hormones are secreted directly into the hypophyseal portal circulation that supplies blood to the anterior pituitary. Once reaching their target cell cluster in the anterior pituitary, the releasing hormones either stimulate or inhibit the synthesis and secretion of anterior pituitary hormones.

How do releasing hormones travel from the hypothalamus to the anterior pituitary gland?

Hypothalamic releasing and inhibiting hormones are carried directly to the anterior pituitary gland via hypothalamic-hypophyseal portal veins. Specific hypothalamic hormones bind to receptors on specific anterior pituitary cells, modulating the release of the hormone they produce.
