How do the releasing hormones that are made in the hypothalamus travel to the anterior pitui-tary?
a. Vessels of the zona fasciculata
b. Chromophils
c. Median eminence
d. Hypophyseal portal system
ANS: D
Neurons in the hypothalamus secrete releasing hormones into veins that carry the releasing hor-mones directly to the vessels of the adenohypophysis via the hypophyseal portal system, thus bypassing the normal circulatory route. Zona fasciculata secretes abundant amounts of cortisol from the adrenal gland. Chromophils are the secretory cells of the adenohypophysis. The median eminence is part of the posterior pituitary, not the anterior.
