The hypothalamic-hypophyseal tract the hypothalamic-hypophyseal tract is the site of prolactin synthesis conducts aldosterone to the hypophysis connects the hypophysis to the pituitary gland is partly contained within the infundibulum

Hypophyseal portal system  is a blood system of vessels in the microcirculation at the base of the brain, connecting the hypothalamus with the anterior pituitary. It is involved in quick transportation and exchange of hormones between the hypothalamus arcuate nucleus and the anterior pituitary gland. Hypothalamic-hypophyseal tract comprises of neurons that deliver vesicles with neurohormones from the hypothalamus to the posterior lobe of the pituitary gland. In this case, it is partly contained within the infundibulum (hollow stalk connecting the hypothalamus and the posterior pituitary gland).
