hormones and delivers them to the posterior pituitary
Which structure of the posterior pituitary is connected to the
median eminence? -
ANSWER-the
infundibular stalk
What form of connection exists between the hypothalamus and
anterior pituitary? - ANSWER-it is vascular, with hormones from
the hypothalamus being released in the blood to influence the
activity of the anterior pituitary
