Quizplus · Accepted Answer

The hypothalamo-hypophyseal tract transports hormones and nerve impulses from the hypothalamus to the posterior pituitary. The hormones released into the bloodstream by the posterior pituitary include oxytocin and antidiuretic hormone, which are synthesized by the hypothalamus. The nerve impulses transmitted through the hypothalamo-hypophyseal tract regulate the release of these hormones in response to different stimuli. The anterior pituitary is regulated by the hypothalamo-hypophyseal portal system, which transports releasing hormones from the hypothalamus to the anterior pituitary. Therefore, choices A and B are incorrect. Choice D is incorrect because the anterior pituitary is not regulated by the hypothalamo-hypophyseal tract.
