Question

Quizplus · Accepted Answer

The hypothalamohypophysial tract, also known as the hypothalamo-neurohypophysial system, is responsible for carrying action potentials from the hypothalamus to the posterior pituitary, which in turn causes the release of hormones such as oxytocin (and ADH, antidiuretic hormone). This system involves neuronal connections rather than a vascular connection, which is characteristic of the hypothalamo-hypophyseal portal system connecting the hypothalamus with the anterior pituitary.
