The pituitary gland is often thought of as the master endocrine gland because of its regulatory role over other endocrine glands. make an argument in favor of designating the hypothalamus as the master endocrine gland instead of the pituitary gland. use specific examples of endocrine pathways to show how the hypothalamus interacts with the anterior and posterior lobes of the pituitary gland in a regulatory manner. also describe the physical structures through which the hypothalamus communicates with each lobe.
